Abstract Novel push-pull fluorescent dyes, 7-(diethylamino)furo[3,2-c]coumarin and 7-(diethylamino)thieno[3,2-c]coumarin derivatives, were designed and synthesized using formyl derivatives of furo- and thieno[3,2-c]coumarins as key intermediates. Electron absorption and emission spectra of the dyes were recorded in different solvents. The longest-wave bands in the electron absorption spectra of the
摘要 使用呋喃和呋喃的甲酰衍生物设计并合成了新型推拉荧光染料 7-(二乙氨基)呋喃[3,2-c]香豆素和7-(二乙氨基)噻吩并[3,2-c]香豆素衍生物。噻吩并[3,2-c]香豆素作为关键中间体。在不同溶剂中记录染料的电子吸收和发射光谱。染料的电子吸收光谱中最长的波段被认为具有推挽性质。
