YieldReaction ConditionsOperation in experiment
87% Under the protection of argon, 0.33 g of <strong>[2351-36-2]2,6-naphthalenedicarboxylic acid chloride</strong>, 60 mL of dichloromethane, 0.15 g of triethylamine (TEA), and 0.88 g of T8-type aminosilsesquioxane were sequentially added to a 100 mL round bottom flask. The magnets were stirred and slowly warmed to room temperature for overnight. After the completion of the reaction, the reaction solution was washed twice with a hydrochloric acid aqueous solution of pH=2, a saturated aqueous sodium chloride solution and deionized water, and the organic phase was dried over anhydrous sodium sulfate. Purification, the eluent is dichloromethane:methanol=15:1 (v:v), and the liquid of the obtained specific ribbon is concentrated and dried.After vacuum drying, 0.93 g of a white solid was obtained, yield 87%.

YieldReaction ConditionsOperation in experiment
92% To a two-necked round-bottom flask under a nitrogen purgewas added 0.460 g of 4,6-dibromothieno[3,4- c ]furan-1,3-dione(1.47 mmol, 1 equiv), 1.350 g of aminopropyl isobutyl POSS(1.54 mmol, 1.05 equiv) and freshly distilled THF (5 mL). The reactionwas allowed to reflux at 50 C for 4 h with a good stirringunder a continuous nitrogen purge. After 4 h reflux, the mixturewas brought to room temperature and all volatiles were evaporatedunder reduced pressure. Then, 3 mL of thionyl chloride wasintroduced to the raw precipitate at room temperature and thetemperature of the mixture was adjusted to 55 C under vigorousstirring and refluxed for 3 h. After cooling, the mixture wasadded dropwise into 75 mL of a cold water-methanol mixture (2:1,v:v) to obtain a white precipitate. The obtained precipitate wasfiltrated and washed with excess acetonitrile. After drying, POSSsubstituted compound is acquired in 92% yield. The acceptor unitwas used directly without further purification. 1 H NMR (400 MHz,CDCl 3 ) δ (ppm): 3.59 (t, J = 6.5 Hz, 2H), 1.94 - 1.78 (m, 7H), 1.78- 1.68 (m, 2H), 0.95 (d, J = 6.3 Hz, 42H), 0.65 - 0.53 (m, 16H);13 C NMR (100 MHz, CDCl 3 ) δ (ppm): 160.2, 134.8, 112.8, 41.3, 25.5,23.9, 22.5, 22.4, 21.8, 9.5.
