Abstract: Three indotricarbocyanine dyes with bis(1,2-diphenyl-1,2-ethylenedithiolato) nickel complex anion were synthesized. Their structures were characterized by IR, 1H NMR spectroscopy and elementary analysis. Electronic absorption spectra, solubilities and photostabilities were also studied. The results show that introducing nickel complex anion improved photostabilities but reduced the solubilities of dyes in organic solvent.

Key words: indotricabocyanine, complex, photostability
