The results have indicated that the introduction of electron-donating methoxy or electron-withdrawing cyano-group at the 7-position of 3-phenylcoumarins caused a bathochromic shift for both absorption and fluorescence spectra. The phenyl group at the 4-position derivative has a hypsochromic shift for both absorption and fluorescence spectra.
结果发现，在3-苯基香豆素的7-位引入给电子基团甲氧基或吸电子基团氰基均使它们的吸收光谱和荧光光谱产生红移，4-苯基香豆素的衍生物的吸收光谱和荧光光谱均产生蓝移。3-苯基香豆素衍生物与4-苯基香豆素的衍生物的基态和激发态的电子转移方向相反。

From the UV-vis absorption spectra data, we can obtained: a Intruduce a 3-sulfopropyl into thiacyanine makes λ〓 red shift 1nm; b For the anionic thiacyanines, the substituent at the 5-position of the benzene ring has influence on λ〓· Acroding to the sequence F, Cl, CH〓, OCH〓, 4, 5-benzo,λ〓 red shift. Strong electron-withdrawing group CF〓 makes λ〓 hypsochromic shift 1nm.
选取三个系列的15个染料在乳剂中作增感实验，并用摄谱仪测定了乳剂的感色峰，结果表明：吸电子取代基不利于增感，给电子取代基有利于增感；噻菁染料的加入扩大了乳剂的感色范围，弥补了卤化银乳剂在465～505nm范围内感光度的不足。
