Abstract
A number of bis(nullomethylidyne)- and nullomethylidynedimethylidynedimerocyanines that are rhodanine derivatives with 3,3-dimethylindolenine, benzothiazole, 4,5-diphenylthiazole, and pyridine residues were obtained. The color of the dimerocyanines depends on the basicity of the nitrogen-containing heterocyclic residue and the length and position of the external polymethine chain. A sharp increase in the sensitizing ability is observed on passing from nullomethylidynedimethylidynedimerocyanines to dimethylidynenullomethylidynedimerocyanines.
