structure with different alkyl chains and the ending chlorine substitution. Single-crystal structure studies and analysis of opto-electronic properties were carried out to understand the structure–property relationships for applying these π-scaffolds in organic single-crystal transistors. Charge mobility studies reveal a promising hole mobility of 0.64 cm2 V−1 s−1 for one of the asymmetric S,N-heterocyclics
我们在本文中描述了具有稠合六元环的三种新型π-共轭梯形和不对称S,N-杂环的设计,合成,表征和性能评估。独特的分子设计在一个分子骨架中结合了缺电子的吡嗪和给电子的噻吩并噻吩,以实现具有六个连续环的稠合和不对称杂环,并调整了具有不同烷基链和末端氯取代基的分子结构。进行了单晶结构研究和光电性能分析,以了解将这些π支架应用于有机单晶晶体管中的结构-性质关系。电荷迁移率研究表明,空穴迁移率有望达到0.64 cm 2 V -1 s对于不对称的S,N-杂环之一,为-1。
Effect of conjugation length on the properties of fused perylene diimides with variable isoindigos
have successfully synthesized four fused hybrid diimide and diamide arrays with different effective conjugation lengths of perylene diimides and isoindigos. These arrays with varying numbers of amides and imides are an efficient strategy to fine-tune the opto-electronic properties, conformation, energy levels and device performance. It is shown that additional fused isoindigos lead to much lower electron
isoindigo (PzIIG) was designed and synthesized as a novel electron acceptor to construct two D–A conjugated polymers, PzIIG-BDT2TC8 and PzIIG-BTT2TC10. Both the polymers were successfully applied in polymersolarcells, and the PzIIG-BDT2TC8 based solarcell device exhibited a PCE of 5.26% with a high Voc over 1.0 V.
