制备了2,5 -二芳基富勒吡咯烷和1,1 -二芳基甲烷富勒烯衍生物与聚（3-己基噻吩）（P3HT）为受体配合物的OPV器件，并对其OPV性能进行了研究。用2,5 -二酰基fulleroprolidine制备的OPV器件的PCE值与取代基的立体化学和性质有关：使用反式- 2,5 -二苯基fulleroprolidine、顺式- 2,5 -二（噻吩-3-基）fulleroprolidine和反式- 2,5 -二（噻吩-3-基）fulleroprolidine的器件的PCE值通过PEDOT: PSS显著降低。另一方面，顺式- 2,5 -二苯基富勒吡咯烷和噻吩-2-基取代化合物的两种异构体以不同的模式起作用：它们与PEDOT: PSS的存在无关。我们进一步发现1,1 -二芳基甲烷烯衍生物也不依赖于PEDOT: PSS的存在，并显示出良好的PCE值。富勒烯及其衍生物由于具有良好的物理和化学性质而受到人们的广泛关注。富勒烯最显著的特点是其光学和电化学性能，最近被应用于以π共轭聚合物如聚（3-己基噻吩）（P3HT）为代表的p型材料组成的有机光伏（OPV）器件中的n型材料。虽然甲基[6,6]-苯基- c61 -丁酸酯（[C60]- pcbm） 4是富勒烯衍生物中应用最广泛的n型材料，但我们最近报道了一些使用富勒吡咯烷作为P3HT受体材料的OPV器件，特别是1-(2-（2-甲氧基乙氧基）-2-芳基富勒吡咯烷16,7比使用[C60]- pcbm的器件具有更高的功率转换效率（PCE）（图1）。
OPV devices which have 2, 5-diarylfulleropyrrolidine and 1, 1-diarylmethanofullerene derivatives as acceptor partners with poly (3-hexylthiophene)(P3HT) were fabricated and their OPV performances investigated. PCE values of OPV devices prepared with 2, 5-diarylfulleropyrrolidines depended on both the stereochemistry and nature of the substituent: PCE of those using trans-2, 5-diphenylfulleropyrrolidine, cis-2, 5-di (thiophen-3-yl) fulleropyrrolidine and trans-2, 5-di (thiophen-3-yl) fulleropyrrolidine were significantly lowered by PEDOT: PSS. On the other hand, cis-2, 5-diphenylfulleropyrrolidine and both isomers of thiophen-2-ylsubstituted compounds worked in a different mode: these are independent of the presence of PEDOT: PSS. We further found that 1, 1-diarylmethanofullerene derivatives also are independent of the presence of PEDOT: PSS and showed good PCE values.A fullerene and its derivatives have attracted much attention due to their attractive physical and chemical properties. 1, 2 The most notable features of fullerenes are their optical and electrochemical properties, which have recently been applied to an n-type material in organic photovoltaic (OPV) devices composed of p-type materials typified by π-conjugated polymers such as poly (3-hexylthiophene)(P3HT). 3 Although methyl [6, 6]-phenyl-C61-butylate ([C60]-PCBM) 4 has been the most widely used the n-type material among fullerene derivatives, 5 we recently reported that some OPV devices using fulleropyrrolidines as acceptor materials with P3HT, in particular, 1-(2-(2-methoxyethoxy) ethyl)-2-arylfulleropyrrolidine 16, 7 showed higher power conversion efficiency (PCE) than those using [C60]-PCBM (Figure 1).
