Abstract

4,4′-Tetramethylene- and 4,4′-pentamethylenebisflavylium salts and their sulfur- and selenium-containing analogs were synthesized. Trimethinecyanine dyes with ethylene and trimethylene bridged groupings in the chromophore were obtained from these salts. The factors that affect the color of these dyes were analyzed thoroughly.
