DIMETHYLIDYNEMEROCYANINOCYANINES - SUBSTITUTED BENZIMIDAZOLE DERIVATIVES

Dimethylidynemerocyaninocyanines-substituted benzimidazole derivatives-were synthesized.A decrease in the basicity of the benzimidazole ring with intensification of the electronegative properties of the substituent gives rise to a small (up to 10 nm) heightening of the color of the dyes obtained.The latter are rather effective spectral sensitizers of silver halide photogralhic emulsions.
