Some new indolo-3,3'-trimethinecyanines, derived from 1,2-dimethyl and 1-methyl-2-arylindole and substituted in the external polymethine chain with halogen, methyl, aryl, and cyano, have been synthesized.The effects of the substituents in the external polymethine chain on the spectral characteristics of the indolotrimethinecyanines are discussed, taking into account delocalization of electron density in the chromophore and steric effects, together with the polarographic and photographic properties of these dyes.
