New dioxopyrrolopyrrole (DPP) derivatives bearing electron-withdrawing groups have been synthesized, and their photophysical properties and redox behaviors have been examined. The electron-accepting abilities of the derivatives were elucidated by cyclic voltammetry (CV) and redox titration analysis. The introduction of the electron-withdrawing groups modulated the redox properties of the DPP core,
已经合成了带有吸电子基团的新型二氧代吡咯并吡咯 (DPP) 衍生物,并研究了它们的光物理性质和氧化还原行为。通过循环伏安法(CV)和氧化还原滴定分析阐明了衍生物的电子接受能力。吸电子基团的引入调节了 DPP 核心的氧化还原特性,并且 1,1,4,4-四氰基丁二烯 (TCB) 部分的添加创建了一个多氧化还原系统。TD-DFT(瞬态密度泛函理论)的应用揭示了化合物的HOMO和LUMO,计算结果与化合物的光物理和电化学性质一致。
