根据我们小组开发的将四硫富瓦烯（TTF）单元引入共轭聚合物体系的方法，我们研究了将TTF作为供体组分的低带隙聚合物。该聚合物基于稠合噻吩并-TTF单元和基于二酮基吡咯并吡咯（DPP）分子的第二共聚单体，所述稠合噻吩并-TTF单元能够将TTF单元直接并入聚合物中。这些单元代表供体-受体共聚物系统p（DPP-TTF），其在光谱的UV-可见光区域中显示出强吸收。优化的p（DPP-TTF）聚合物有机场效应晶体管和单一材料有机太阳能电池器件表现出优异的性能，空穴迁移率高达5.3 × 10 - 2cm 2/（Vs），功率转换效率（PCE）为0.3%。p（DPP-TTF）与苯基-C71-丁酸甲酯（PC 71 BM）共混的体异质结有机光伏器件的PCE为1.8%。
Following an approach developed in our group to incorporate tetrathiafulvalene (TTF) units into conjugated polymeric systems, we have studied a low band gap polymer incorporating TTF as a donor component. This polymer is based on a fused thieno-TTF unit that enables the direct incorporation of the TTF unit into the polymer, and a second comonomer based on the diketopyrrolopyrrole (DPP) molecule. These units represent a donor-acceptor copolymer system, p(DPP-TTF), showing strong absorption in the UV-visible region of the spectrum. An optimized p(DPP-TTF) polymer organic field effect transistor and a single material organic solar cell device showed excellent performance with a hole mobility of up to 5.3 × 10(-2) cm(2)/(V s) and a power conversion efficiency (PCE) of 0.3%, respectively. Bulk heterojunction organic photovoltaic devices of p(DPP-TTF) blended with phenyl-C71-butyric acid methyl ester (PC71BM) exhibited a PCE of 1.8%.
