二酮吡咯并吡咯(DPP)衍生物是研究最有效的聚合物太阳能电池(PSC)和有机场效应晶体管(OFET)应用材料之一。我们在这里报告了适用于直接杂芳基化聚合反应的新型氟化二噻吩基二酮基吡咯并吡咯(fDT-DPP)单体的合成。然后制备了fDT-DPP共聚物以探测氟化作用。发现与非氟化类似物相比,它们具有更高的HOMO能级和较小的带隙。而且,某些fDT-DPP共聚物在OFET中测试时显示出双极性行为。例如,P2的空穴迁移率最高为0.8 cm 2 V –1 s –1,电子迁移率最高为0.5 cm 2 V –1s –1。对于P5,还获得了具有高达7.5%的功率转换效率(PCE)的反向PSC 。此处报道的这些结果(OFET和PSC)证实了二噻吩基-DPP部分的氟化改善了有机电子器件的性能。这项研究还证明了直接杂芳基化聚合和fDT-DPP作为新型共轭聚合物的优势。

Fluorinated dithienyl-diketopyrrolopyrrole-based polymers and copolymers are disclosed herein. More specifically, fluorinated dithienyl-diketopyrrolopyrrole-based polymers and copolymers for use in organic electronics are disclosed. A process for the preparation of fluorinated dithienyl-diketopyrrolopyrrole-based polymers and copolymers is also disclosed. The fluorinated dithienyl-diketopyrrolopyrrole-based polymers and copolymers are characterized by high electron mobility, high hole mobility and good power conversion efficiencies.
are among the most efficient materials studied for both polymer solar cells (PSCs) and organic field-effecttransistors (OFETs) applications. We report here the synthesis of new fluorinated dithienyldiketopyrrolopyrrole (fDT-DPP) monomers suitable for direct heteroarylation polymerization. fDT-DPP copolymers were then prepared to probe the effect of the fluorination. It was found that they feature deeper
