✦ Synopsis

Abstract

A novel efficient synthesis of 2‐styrylthiazolo[4,5‐b]quinoxaline based fluorescent dyes was achieved by the condensation of 2‐alkylthiazolo[4,5‐b]quinoxaline with selected 4‐N,N‐dialkylamino‐substituted aryl‐aldehydes or hetarylaldehydes in the presence of piperidine or acid anhydride. The coloristic, fluorophoric and dyeing properties of these dyes were studied.
