and its optical properties thoroughly investigated. Fluorescence quenching studies showed that an important fraction of the photogenerated excitons formed in TPAPV is quenched by [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) in blend films, therefore indicating efficient exciton dissociation and potential applications in organic photovoltaic (PV) cells.

合成了一种新的端基为三苯胺基的低聚物型对-亚苯基亚乙烯基(TPAPV),并对其光学性质进行了深入研究。荧光猝灭研究表明,TPAPV中形成的光生激子的重要部分被[6,6]-苯基-C 61-丁酸甲酯(PC 61 BM)猝灭,因此表明有效的激子解离和潜在的应用前景在有机光伏(PV)电池中。制备了包含TPAPV作为电子给体的平面异质结有机光伏电池,结构为ITO / TPAPV(6 nm)/ C 60(50 nm)/ BCP(10 nm)/ Ag的器件表现出开路电压(V OC) ,短路电流(Ĵ SC),填充因子(FF),和0.92 V,2.9毫安厘米的功率转换效率(PCE)-2分别47.8%,和1.23%。
