Abstract

Starting from the products of formylation and vinylformylation of indeno[2,1-b]chromene a series  of new symmetrical and unsymmetrical polymethine  dyes have been synthesized with  a  residue  of indeno[2,1-b]chromene as the terminal group. It was shown that the unsymmetrical dyes obtained have two absorption bands in the visible region, the position, intensity, and shape  of which depend on the nature of the second terminal group.
