Twelve imidazole based Y-shaped push–pull chromophores have been designed, synthesised and fully characterised featuring 4,5-bis(N,N-dimethylanilino)imidazole as a donor moiety, a systematically enlarged π-linker and nitro and cyano groups as acceptors. The synthesised push–pull systems have been studied by electrochemistry, UV/Vis and IR spectroscopy and nonlinear optical properties have been calculated
已设计,合成并充分表征了十二个基于咪唑的Y形推挽生色团,其特征在于4,5-双(N,N-二甲基苯胺基)咪唑为供体部分,系统地扩大了π-连接基,并以硝基和氰基为受体。已通过电化学,UV / Vis和IR光谱研究了合成的推挽系统,并计算了非线性光学性质。此外,还评估了测量和计算的特性与结构特征之间的定量关系。电化学和光谱性质主要受到强共轭受体,大π接头的存在以及发色团的空间排列的影响。
