Cu (II)-Organic Coordination Polymer Networks for Persistent Nitric Oxide Release in Tumor Therapy

Jeong, Hyejoong ; Kim, Na Kyung ; Park, Daehwan ; Youn, Heesoo ; Osuji, Chinedum O ; Doh, Junsang

DOI: 10.1021/acs.biomac.4c01071 PubMed ID: 39283833 Biomacromolecules,2024,25(10):6830-6839.

Abstract: Nitric oxide (NO) plays a key role in regulating the immunesystem by polarizing macrophages toward the proinflammatory M1phenotype, which is beneficial for cancer immunotherapy. We developeda Cu-organic coordination polymer network to sustainably release NO fromendogenous donors. This robust polymer network was constructed througha dual-interaction process: complexation and cross-linking. The carboxylategroups of deprotonated 4-((6-(acryloyloxy)hexyl)oxy)benzoic acid (BA)served as bidentate ligands for the formation of Cu(II) complexes. Theacrylate moiety of BA anchored these complexes in the polymer network,forming a cross-linked film. Cu ions within the network catalyticallypromoted NO release from S-nitrosoglutathione, maintaining this releaseeven after 90 days in a physiological environment. The released NOeffectively polarized both resting (M0) and tumor-promoting (M2)macrophages to the M1 phenotype. With their demonstrated physiological stability and sustained NO release performance, BA-Cu films hold potential as anticancer patches capable of continuously promoting antitumoral macrophages.

Direct Ink Writing of 4D Structural Colors

Jeroen A. H. P. Sol ; Luc G. Smits ; Albert P. H. J. Schenning ; Michael G. Debije ;

DOI: 10.1002/adfm.202201766 Adv. Funct. Mater.,2022,32(30):2201766.

Abstract: Additive manufacturing with stimuli-responsive materials—4D printing—is a rapidly growing field, with direct ink writing allowing deposition of a wide variety of materials. The synthesis of a humidity-sensitive cholesteric liquid crystal oligomer ink is reported. With the responsive cholesteric ink, demonstrator devices exhibiting the ink's “four dimensionality” are printed in disparate fashions: as a structural color change or as a preprogrammed deformation mode. After printing, the photonic ink changes color in response to atmospheric humidity, demonstrated as a hydrochromic coating precisely deposited atop a 3D-printed beetle. After activation in aqueous acid, the beetle exhibits vibrant color shifts across the visible spectrum. Alternatively, a scallop-inspired actuator with a 3D-programmed structural color is selectively treated with acid, to allow reversible “opening” and “closing” when exposed to humid and dry air, respectively. The ink enables additive manufacturing of both monolithic and multimaterial stimuli-responsive, shape-changing, structurally colored objects, toward broad application of cholesterics in future “smart,” 4D structurally colored devices.

A pH-Responsive Liquid Crystal Hydrogel Actuator with Calcium-Induced Reprogrammable Shape Fixing

Houben, Simon J. A. ; Lugger, Sean J. D. ; van Raak, Roel J. H. ; Schenning, Albert P. H. J. ;

DOI: 10.1021/acsapm.1c01686 ACS Appl. Polym. Mater.,2022,4(2):1298-1304.

Abstract: Soft polymer actuators have myriad applications and have therefore gained considerable attention in recent years. However, it remains challenging to prepare soft actuators with predefined shapes. Here, a bilayer polymer actuator with a (re)programmable shape is prepared from a microporous anisotropic polypropylene scaffold and a thin, pH-responsive liquid crystalline network (LCN) layer. The hydrogen bonds between dimerized benzoic acid derivatives in the LCN can be disrupted by an alk. treatment, resulting in a pH-responsive LCN hydrogel layer. The pH-responsive actuation is governed by both the anisotropic mech. properties of the scaffold and the cross-link d. of the LCN hydrogel. Ca2+ ions can be used to chem. cross-link the actuator resulting in an initial programmed shape. The shape fixing can be reversed by removing the Ca2+ ions with an EDTA (EDTA) solution The shape fixing can be performed locally, resulting in pH-responsive actuators with three-dimensional initial configurations of choice.

Switchable gas permeability of a polypropylene-liquid crystalline composite film

Houben, Simon J. A. ; Kloos, Joey ; Borneman, Zandrie ; Schenning, Albert P. H. J. ;

DOI: 10.1002/pol.20210835 J. Polym. Sci.,2022,60(5):803-811.

Abstract: The development of functionalized polyolefins for use as stimuli-responsive commodity polymers has recently received much attention. In this work, a microporous polypropylene (PP) scaffold is used to align and fortify a smectic liquid crystalline network (LCN) which can switch its gas permeability upon pH changes. The LCN is a photopolymerized liquid crystalline mixture of a dimerized benzoic acid derivative monoacrylate and a diacrylate crosslinker. In the hydrogen-bonded state, the composite membrane shows a high-mol. order and a low permeability for He, N2, and CO2 gases. By pH switching from the hydrogen-bonded state to the salt form, the mol. order is reduced, and the gas permeability is increased by one order of magnitude. This increase is mainly attributed to a loss in order of the system, increasing the free volume, resulting in an increased diffusibility. By exposing the composite film to basic or acidic environments, reversible switching between low and high gas permeability states is observed, resp. The phys. constraints imposed by the PP scaffold strengthens the membrane while the reversible switching inside the liquid crystalline polymer is maintained. This switching of gas permeation properties is not possible with the fragile freestanding LCN films alone.

Cholesteric Liquid Crystals in Additive Manufacturing

DOI: 10.6100/95acbb3d-ab3d-411b-a30c-0be458a2a966 Eindhoven University of Technology,2022.

Abstract: The perception of colour has played a critical role in human development, helping the earliest peoples to judge the ripeness of food, vital for their safety (1, 2). For this reason, human vision has evolved to be most sensitive in the range of 380 to 780 nm (3). Visible colours result from light absorbance, luminescence by pigments, or photonic systems that generate vivid colours via selective reflection of the electromagnetic spectrum as a result of nanoscale arrangement of their constituent materials (4). Using structural rather than pigmental or luminophore-generated colour has some key advantages. First is that structural colour is generally less susceptible to degradation. Secondly, the structured materials may also be made dynamic: when the material is swelled or contracted by exposure to environmental factors, the result may be dramatic colour changes, which could be harnessed for use as sensors (5). As discussed in Chapter 1, liquid crystals (LCs) are positioned to be the basis of many responsive structurally coloured materials. Addition of a chiral dopant to a nematic LC leads to the formation of a light-reflecting chiral nematic phase, inwhich the depth spanned by a 360° rotation of the directors of the LC planes is labelled the “pitch”, p. The product of p, average refractive index ⟨n⟩, and the angle of observation θ yields the wavelength of maximum reflection: λmax = p⟨n⟩ cos (θ). By polymerizing the reactive ChLC monomers into a ChLC network (ChLCN), one makes a step towards materials applicable as photonic plastics. Almost always described in thin-film format, these materials have served as visual security features (6), and indicators for temperature (7, 8), medical conditions (hypo- or hypercalcaemia) (9) or chemical analytes, such as for volatile low molecular weight amines (10). Furthermore, owing to their vibrant, angle-dependent colour, ChLC materials have been used in the decorative coatings industry as effect pigments (11), and recently as organic solvent-responsive coatings (12). An alternative to a fully cholesteric coating is based on spherical cholesteric particles embedded in a non-LC binder, although high concentrations of the particles are required (13).

DOI: 10.1021/acsmaterialslett.1c00222 ACS Mater. Lett.,2021,3(6):704-712.

Abstract: Atomically thin MoS2 nanosheets are of interest due to unique electronic, optical, and catalytic properties that are absent in the bulk material. Methods to prepare nanosheets from bulk material that facilitate studies of 2D-MoS2 and the fabrication of useful devices have consequently assumed considerable importance. Here, we report the simultaneous exfoliation and stable dispersion of MoS2 nanosheets in a liquid crystal. Exfoliation of bulk MoS2 in mesogen-containing solutions produced stable dispersions of 2D-MoS2 that retained suspension stability for several weeks. Solvent removal in cast films yielded nanocomposites of 2D-MoS2. Preservation of single- and few-sheet MoS2 was confirmed utilizing UV–vis and Raman spectroscopy in the nematic and isotropic fluid states of the system and, remarkably, in the solid crystal as well. Importantly, the MoS2 nanosheets remained well-dispersed upon polymerization of the reactive mesogen to form a liquid crystal polymer. The ability to stably disperse 2D-MoS2 in a structured fluid opens up new possibilities for studying anisotropic properties of MoS2 and for exploiting such properties in responsive materials.

DOI: 10.1021/acsami.0c20898 PubMed ID: 33539067 ACS Appl. Mater. Interfaces,2021,13(6):7592-7599.

Abstract: Bottom-up methods for the fabrication of nanoporous polymer membranes have numerous advantages. However, it remains challenging to fabricate nanoporous membranes that are mech. robust and have aligned pores, i.e., with a low tortuosity. Here, a mech. robust thin-film composite membrane was fabricated consisting of a two-dimensional (2D) porous smectic liquid crystalline polymer network inside an anisotropic, microporous polymer scaffold. The polymer scaffold allows for relatively straightforward planar alignment of the smectic liquid crystalline mixture, which consisted of a diacrylate crosslinker and a dimer forming benzoic acid-based monoacrylate. Polymerized samples displayed a smectic A (SmA) phase, which formed the eventual 2D porous channels after base treatment. The aligned 2D nanoporous membranes showed a high rejection of anionic solutes bigger than 322 g/mol. Cleaning and reusability of the system were demonstrated by intentionally fouling the porous channels with a cationic dye and subsequently cleaning the membrane with an acidic solution After cleaning, the membrane properties were unaffected; this, combined with numerous pressurizing cycles, demonstrated reusability of the system.

DOI: 10.1002/adpr.202000115 Adv. Photon. Res.,2021,2(4):2000115.

Abstract: Responsive materials that alter their color in response to environmental changes can be used as optical sensors. Chiral nematic liquid crystals are photonic materials that selectively reflect specific wavelengths of light and have been made environmentally responsive. Herein, the use of ultrasonication of responsive cholesteric liquid-crystal network films to form structurally colored flakes that demonstrate color changes when moved from an aqueous to dry environment and back again is demonstrated, which suggests a scalable technique to form quantities of responsive particles that could conceivably be embedded in permeable hosts to allow the optical detection of humidity or certain chemical species.

Directed Assembly of Anisotropic Inorganic Nanomaterials Using Self-Assembled Soft Mesophases

Gabinet, Uri Roei ;

Abstract: Anisotropic nanomaterials have propelled new technologies and materials in diverse fields ranging from electronics and photonics to catalysis and biomedicine. While initially nanomaterials’ utilization in application focused on their unique properties which are a direct result of their confinement to the nanoscale, such as size-dependent fluorescence or bandgap, more recently, additional properties and enhanced functionality are sought after by controlling the spatial organization and orientation of nanomaterials. Such advanced functionality can be enabled by controlling the juxtaposition of nanomaterials, eliciting an array-geometry-dependent effect from multiple individual nanostructures collectively interacting with one another, as is evident in plasmonic metamaterials. Another possibility for complex functionality can be achieved by altering the orientation of anisotropic nanomaterials, achieving direction-selective properties, such as polarized emission or direction-selective conductivity in 1D nanorods or 2D nanosheets. In order to fully realize the potential in nanomaterials, as presented above, reliable methodologies are needed to achieve both spatial and orientational control of anisotropic nanomaterials. A possible handle to do so is their embedment in a soft-matter matrix. Soft materials are inexpensive, easy to modify and can be made compatible with multiple inorganic nanomaterials. Some, such as block-copolymers (BCPs), create arrays or ordered features on multiple length-scales, from just a few- to hundreds- of nanometers. Others, such as liquid crystals (LCs), are stimuli responsive and can drive the alignment and reorientation of embedded 1D nanorods or 2D sheets. This dissertation explores two main themes to achieve positional and orientational control over anisotropic nanomaterials, exemplified by two model systems: 1D ZnO nanorods and 2D MoS2 nanosheets. First, we explore BCP templated Au covered ZnO nanorod arrays, and their emerging optical properties dictated by the BCP template, and realized as a platform for surface enhanced Raman scattering (SERS) or direct plasmonic sensing. In addition, other optical effects elicited by such a platform are explored, including it being an ‘epsilon-near-zero’ (ENZ) material, or ones resulting from the BCP template being a disordered hyperuniform (DH) material. The second part of this dissertation switches gears and discusses orientation control of 2D MoS2 nanosheets in LC matrices. 2D-MoS2 was dispersed for the first time in thermotropic LCs and subsequently magnetically aligned, revealing anisotropic optical effects. This result opens up a pathway for the incorporation of 2D-MoS2 into LC-based systems and the study of MoS2’s anisotropic properties. Finally, we explore 2D-MoS2 dispersed into a lyotropic LC phase, and examines the transport properties of planarly stacked MoS2 in membrane applications. Overall, this dissertation introduces new techniques to enable positional and orientational control over anisotropic nanomaterials by embedding them in soft-matter matrices, and by doing so enables new functional properties which can be utilized in advanced applications.

Abstract: With the advent of direct laser writing using two-photon polymerization, the generation of high-resolution three-dimensional microstructures has increased dramatically. However, the development of stimuli-responsive photoresists to create four-dimensional (4D) microstructures remains a challenge. Herein, we present a supramol. cholesteric liquid crystalline photonic photoresist for the fabrication of 4D photonic microactuators, such as pillars, flowers, and butterflies, with submicron resolution These micron-sized features display structural color and shape changes triggered by a variation of humidity or temperature These findings serve as a roadmap for the design and creation of high-resolution 4D photonic microactuators.

Yield	Reaction Conditions	Operation in experiment
	With thionyl chloride; In tetrahydrofuran; at 0℃; for 0.5h;	4-{ [6-(acryloyloxy)hexyl]oxy}benzoic acid (4) (2.8g) was dissolved in tetrahydrofuran (THF) (1 OQnI) at room temperature, and the resulting mixture was then adjusted to O0C. Then, thionyl chloride (12ml, IM in THF) was added to the mixture, and the resulting mixture solution was stirred for 30 minutes. Subsequently, 4-(6-bromohexyloxy)phenol (2.5g) and triethylamine (13ml) were added to the mixture solution, and the resulting mixture is stirred at O0C for one hour, and then stirred at room temperature overnight. Then, an aqueous saturated ammonium chloride solution was poured into the reaction mixture to stop the reaction. The reaction product was extracted three times with ethyl acetate (5QnI) (5QnI x 3). After removing water with magnesium sulfate and evaporating the solvent, the reaction product was refined by column chromatography (eluent: ethyl acetate/hexane=l/2) to obtain 4-(6-bromo hexyloxy) phenyl 4-{ [6-(acryloyloxy)hexyl]oxy}benzoate (5) (3g).
	With oxalyl dichloride;N,N-dimethyl-formamide; In toluene; at 0 - 20℃;	1.02 g (3.50 mmol) of 4-(6-acryloyloxyhexyloxy)benzoic acid was dissolved in 10 ml of toluene, and 0.33 ml of oxalyldichloride and then one drop of N,N-dimethylformamide was added under ice cooling while stirring. After removing an ice bath and stirring at room temperature for 2 hours, toluene was distilled off under reduced pressure to prepare 4-(6-acryloyloxyhexyloxy)benzoic acid chloride. 1.00 g (1.52 mmol) of the compound No. B-1 obtained in Example 6 was suspended in 50 ml of pyridine, and a solution prepared by dissolving the acid chloride prepared by the above method in 3.0 ml of tetrahydrofuran was added at room temperature. After stirring at room temperature for 4 hours, the reaction solution was poured into an aqueous 1 N hydrochloric acid, followed by extraction with dichloromethane. The organic layer was washed in turn with an aqueous 2 N hydrochloric acid and water, and then dried over anhydrous magnesium sulfate. The organic layer was filtered, and the solvent was distilled off under reduced pressure, and then the residue was purified by silica gel column chromatography (eluant: dichloromethane/methanol/acetic acid = 20/1/1 to 10/1/1). A fraction containing the objective product was washed with water, and the solvent was distilled off under reduced pressure to obtain 0.70 g (yield: 38percent) of a compound B-8.
