Abstract: Several triearbocyanine and tetramethinestyryl-cyanine dyes containing indole end group were synthesized from trimethylindoline quaternary salt. The structures of the dyes were confirmed by elemental analyses, IR spectra and 1HNMR spectroscopy. Some indotricarbocyanines with N, N-diphenyl amino group on the meso positions of the bridges of heptamethine chains are well soluble in 1,2-dichloroethane.

Key words: cyanine dye, indole, electronic spectrum, optical recording medium
