Synthesis and Properties of N-Benzylindotricarbocyanine Dyes

Abstract

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 λ_max 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
