Synthesis and Optical Properties of New S-Derivatives of 5,5′-(1,4-Phenylene)bis(4H-1,2,4-triazole-3-thiol) and 5,5′,5″-(Benzene-1,3,5-triyl)tris(4H-1,2,4-triazole-3-thiol)

Abstract

A simple one-pot synthetic method for novel S-alkenyl and propargyl derivatives of 5,5′-(1,4-phenylene)-bis(4H-1,2,4-triazole-3-thiol) and 5,5′,5″-(benzene-1,3,5-triyl)tris(4H-1,2,4-triazole-3-thiol) has been developed. Absorption and luminescence properties of the synthesized compounds have been estimated, and the fluorescence quantum yields have been determined.
