摘要：
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. © 2005 Springer Science+Business Media, Inc.
