摘要： 合成了5种N-苄基吲哚三碳菁染料,通过红外光谱、核磁共振氢谱及元素分析确证了其结构,并研究了电子吸收光谱、荧光光谱、光稳定性及溶解度。结果表明,染料溶液和膜的最大吸收波长均为780～830nm;染料在二氯乙烷中的溶解度大于在乙醇中的溶解度;氮原子上苄基的引入极大地改进了染料的光稳定性(与HITCI比较).

关键词: 吲哚三碳菁染料, 光学性能, 光稳定性

Abstract: Five N-benzylindotricarbocyanine dyes were synthesized,all of which are new compounds and have not been reported yet.Their structures were confimed by IR,1H NMRspectroscopy and elementary analysis.Electronic absorption spectra,fluorescence emissin spectra,photostabilities and solubilities were also studied.It was found that the λmax of dye solutions and dye films were all within 780～830 nm;the solubilites of dyes in 1,2-dichloroethane were better than those in ethanol;introducing benzyl group on nitrogen atom improved the photostabilities greatly(compared to HITCI)

Key words: Indotricarbocyanine, Optical property, Photostability
