Synthesis and Photophysical Studies of Thiazolidin-2,4-dione Derivatives

Abstract

Thiaaolidin-2,4-dione(1) and its derivative-5-(2- hydroxy benzylidene) thiazolidine-2,4-dione(2) 5-(4- bromo -2- hydroxylbenzylidene)thiazolidine -2,4-dione (3)5-(4- chloro-2-hydroxybenzylidene)thiazolidine-2,4-dione(4) 3-(2,4- dioxothiazolidin-5-ylidne) methyl)-4-hydroxybenzaldehyde(5) have been synthesized.Compound (2) acts as selective chemosensor for Cu2+ ions amongst ions and for cyanide ions amongst another anions of biological importance.
