A number of diarylmethanofullerene derivatives were synthesized. The cyclopropane ring of the derivatives has two aryl groups substituted with electron-withdrawing and -donating groups, the latter with long alkyl chains to improve solubility in organic solvents, an important property in processing cells. First reduction potentials of most derivatives were less negative than that of [6,6]-phenyl-C61-butyric
合成了许多二芳基甲烷富勒烯衍生物。衍生物的环丙烷环具有两个被吸电子和供电子基团取代的芳基,后者具有长烷基链以提高在有机溶剂中的溶解度,这是处理细胞的重要特性。大多数衍生物的第一还原电位比 [6,6]-苯基-C61-丁酸甲酯 (PCBM) 的负值小,这可能归因于它们的吸电子性质。研究了用聚(3-己基噻吩)(P3HT)作为电子供体和二芳基甲烷富勒烯衍生物作为电子受体材料制造的有机薄膜光伏电池。(甲氧基羰基)苯基[双(辛氧基)苯基]甲烷}富勒烯显示出与PCBM一样高的功率转换效率,但在多种有机溶剂中的溶解度高于 PCBM。V(oc) 值高于 PCBM,后者源自给电子(辛氧基)苯基,可能会提高 LUMO 水平。还研究了用具有一些吸电子基团的衍生物制造的器件的光伏效应。
