Abstract

Abstract We have developed procedures for the synthesis of push–pull azo-chromophores containing the s-triazolo [3, 4-b] thiadiazole heterocycle compatible with the presence of electron-acceptor groups (nitrophenyl group) as substituents on both the triazole and thiadiazole rings. The linear and non-linear optical properties of the synthesized chromophores have been characterized by the EFISH technique, electro-optical ...
