Abstract

Triethylammonium salt of pyran semisquaraine reacted with N-methyl-substituted heterocyclic salts to give unsymmetrical di-tert-butyl-substituted squarylium dyes. The effect of the terminal heterocycles on the spectral properties of the obtained dyes was studied, and the electronic structure of squaraines and electronic transitions therein were analyzed by quantum chemical methods.
