Twelve novel DâÏâA chromophores with the N,Nâ²-dibutylbarbituric acid acceptor, the N,N-dimethylamino donor and a systematically extended Ï-linker were synthesized. The extent of intramolecular charge-transfer, structureâproperty relationships and nonlinear optical properties were further investigated by X-ray analysis, electrochemistry, UV/Vis absorption spectra, calculations and EFISH experiments.
合成了具有N,N'-二丁基巴比妥酸受体、N,N-二甲基氨基供体和系统性延长的π连接体的十二种新型D-π-A型色团。通过X射线分析、电化学、紫外/可见吸收光谱、计算和EFISH实验进一步研究了分子内电荷转移程度、结构-性质关系和非线性光学性质。
