摘要：Five N-benzylindotricarbocyanine dyes were synthesized, all of which are new compounds and have not been reported yet, Their structures were confimed by IR, H-1 NMR spectroscopy and elementary analysis, Electronic absorption spectra, fluorescence emissin spectra, photostabilities and solubilities were also studied. It was found that the lambda(max) of dye solutions and dye films were all within 780 similar to 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).
