diketopyrrolopyrrole (DPP) with a high yield up to 90%. The completely overlapping molecules, which in general case would cause aggregation-induced quenching (ACQ) effect, can unexpectedly emit in both solvent and solid state (solid-state fluorescent quantum yield up to 30%). The term “beauty” has been verified by various types of optical spectra, while luminescence mechanism is systematically investigated
在人类漫长的历史长河中,“美”一直是人类文明的终极追求。在这项工作中,我们报告了一种基于老牌颜料二酮吡咯并吡咯 (DPP) 的漂亮荧光材料的合成,产率高达 90%。完全重叠的分子,在一般情况下会导致聚集诱导猝灭 (ACQ) 效应,可以意外地在溶剂和固态中发射(固态荧光量子产率高达 30%)。“美丽”一词已通过各种类型的光谱得到验证,而发光机制则通过单晶 X 射线衍射 (XRD)、时间相关密度泛函理论 (TD-DFT) 计算和浓度相关吸收进行系统研究/排放。观察到自组织过程。
