To shed light on intramolecular charge‐transfer phenomena in 1,2,3‐triazole‐linked materials, a series of 1,2,3‐triazole‐linked push–pull chromophores were prepared and studied experimentally and computationally. Investigated modifications include variation of donor and/or acceptor strength and linker moiety as well as regioisomers. Photophysical characterization of intramolecular charge‐transfer features
为了阐明1,2,3-三唑连接的材料中的分子内电荷转移现象,制备了一系列1,2,3-三唑连接的推挽生色团,并进行了实验和计算研究。研究的修饰包括供体和/或受体强度和接头部分以及区域异构体的变化。分子内电荷转移特征的光物理特征揭示了三唑连接基的双极性行为,具体取决于取代位置。此外,对非中心对称材料进行了二次谐波生成测量,结果表明此类材料具有很高的非线性光学活性。
