Asymmetric polymethine dyes based on thiazolo[3,2-a]quinoxalinium salts

Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Asymmetric carbocyanine dyes, the solutions of which are characterized by the presence of several absorption bands in the visible and near-IR regions, were synthesized from 4,5-dimethyl-1-oxo-2-phenyl-1,5-dihydrothiazolo[3,2-a]quinoxalin-3-ium perchlorate. Their deep color is due both to a more effective length of the condensed heterocyclic system and to the strong interaction of the electronic transitions, localized on the polymethine chain and on the heterocyclic ring.
