备注

采用Prato反应合成了一系列N-苯基取代的富勒烯吡咯烷衍生物并将其作为电子受体材料应用于聚合物太阳能电池.实验结果表明,N-苯基-2-(3-甲氧基苯基)[60]富勒烯吡咯烷(FP2)和N-苯基-2-(4-甲氧基苯基)[60]富勒烯吡咯烷(FP3)可以通过一锅法合成,其合成过程简单,成本较低且产率较高.以聚(3-己基噻吩)(P3HT)为给体,FP2和FP3为受体的聚合物太阳能电池的能量转换效率分别为3.27%和3.30%.该效率接近在相同实验条件下的P3HT:[6,6]-苯基-C61-丁酸甲酯(PC61BM)器件以及文献报道的P3HT:PC61BM器件的效率.

A series of fulleropyrrolidine derivatives with N-phenyl group were prepared via Prato reaction and employed as acceptors for polymer solar cells.It was found that N-phenyl-2-(3-methoxyphenyl)[60] fulleropyrrolidine(FP2)and N-phenyl-2-(4-methoxyphenyl)[60] fulleropyrrolidine(FP3)had been successfully synthesized via a facile,cost-effective one-pot reaction with high yield.FP2 and FP3 worked as good electron acceptors with poly(3-hexylthiophene)(P3HT)as donor,and power conversion efficiencies of 3.27% and 3.30% were obtained,respectively.These efficiencies are comparable to that of the P3HT:[6,6]-phenyl-C61-butyric acid methyl ester(PC61BM)device under the same experimental conditions and that of the reference P3HT:PC61BM device reported in the literature.
