series of push-pull butadiene dyes (new merocyanine dyes) containing 3,6-bis(dimethylamino)fluorenylidene, thioxanthenylidene, or 10-(9-xanthenylidene)-9(10H)-anthrylidene chromophore was easily synthesized from the corresponding 1,1-diaryl-2-propyn-1-ol systems. Their absorption spectral properties were examined and the relationship between their light absorption properties and chemical structures is
一系列含有 3,6-双(二甲氨基)芴、噻吨或 10-(9-xanthenylidene)-9(10H)-anthrylidene 生色团的推拉丁二烯染料(新型部花青染料)很容易从相应的 1、 1-二芳基-2-丙炔-1-醇系统。研究了它们的吸收光谱特性,并与 PPP-SCF-CI-MO 计算的结果进行了比较,讨论了它们的光吸收特性和化学结构之间的关系。研究了溶剂极性对染料 1⁄λmax(=波数)-值的影响,并将溶剂致变色性质与已知的溶剂极性参数如 ET30、Z、χR、πazo* 对 2-[2 -[3,6-双(二甲氨基)芴基]亚乙基]-1,3-茚二酮。
