Abstract

The reaction of methylamine with symmetrical 4,6,4′,6′-tetraphenyl-substituted 2-pyrylopolycarbocyanines, in which both a positions of the polymethine chain are linked to the β positions of the heterocyclic residues by trimethylene groups, was used to synthesize the corresponding pyridopyrylocyanines. The effect of trimethylene groupings in the 2-pyridocyanines on this transformation was examined. The principles involved in the color of the synthesized pyridopyrylocyanines were studied.
