由6-氯己基甲基丙烯酸酯和甲基丙烯酸甲酯的无规共聚物衍生的含叠氮化物的共聚物与c60在氯苯中反应,得到c60含量高达41.4%的聚甲基丙烯酸酯,可溶于常见的有机溶剂,如CHCl3、THF和甲苯。SEC色谱表明,共聚物在CHCl3中形成了分子内和分子间的聚集,这可能是由于悬垂的c60基团之间的强相互作用,而在THF中没有观察到聚集。所得聚合物的带隙小于C60,而LUMO能级为与聚(3-己基噻吩)(P3HT)界面的电荷解离提供了0.6 eV的能量驱动力。P3HT共混物具有较高的荧光猝灭效率和较高的voc。
Azide-containing copolymers derived from random copolymers of 6-cholorohexyl methacrylate and methyl methacrylate were reacted with C60in chlorobenzene to afford polymethacrylates with high C60content up to 41.4 wt% soluble in common organic solvents such as CHCl3, THF, and toluene. The SEC chromatograms implied that the obtained copolymers formed intra- and inter-molecular aggregation in CHCl3, presumably due to the strong interaction between the pendant C60moieties, whereas no aggregation was observed in THF. Band gap of the obtained polymer was lower than that of C60,while the LUMO level provided 0.6 eV of energetic driving force for charge dissociation at the interface with poly(3-hexylthiophene) (P3HT). The blend with P3HT exhibited high fluorescence quenching efficiency and higherVoc.
