A new semiconducting polymer, PDPP3T, with alternating diketopyrrolopyrrole and terthiophene units is presented. PDPP3T has a small band gap of 1.3 eV and exhibits nearly balanced hole and electron mobilities of 0.04 and 0.01 cm(2) V(-1) s(-1), respectively, in field-effect transistors (FETs). By the combination of two identical ambipolar transistors, an inverter was constructed that exhibits a gain of approximately 30. When PDPP3T was combined with [60]PCBM or [70]PCBM in a 1:2 weight ratio, photovoltaic cells were made that provide a photoresponse up to 900 nm and an AM1.5 power conversion efficiency of 3.8 or 4.7%, respectively. In contrast to the almost constant FET mobility, the efficiency of the photovoltaic cells was found to be strongly dependent on the molecular weight of PDPP3T and the use of diiodooctane as a processing agent.

用于双极逻辑和光伏的聚（二酮吡咯并吡咯-三联噻吩）

提出了一种新的半导体聚合物 PDPP3T，它具有交替的二酮吡咯并吡咯和三噻吩单元。PDPP3T 具有 1.3 eV 的小带隙，并且在场效应晶体管 (FET) 中表现出几乎平衡的空穴和电子迁移率分别为 0.04 和 0.01 cm(2) V(-1) s(-1)。通过组合两个相同的双极晶体管，构建了一个增益约为 30 的逆变器。当 PDPP3T 与 [60]PCBM 或 [70]PCBM 以 1:2 的重量比组合时，制成的光伏电池可提供高达 900 nm 的光响应和分别为 3.8% 或 4.7% 的 AM1.5 功率转换效率。与几乎恒定的 FET 迁移率相反，发现光伏电池的效率强烈依赖于 PDPP3T 的分子量和使用二碘辛烷作为加工剂。
