heterocyclic azo dyesbased on the thienylpyrrole system, functionalized with benzothiazol-2-yl (5–6) or benzothiazol-6-yl acceptor groups (7) through an NN bridge, have been synthesized by azo coupling using 1-alkyl(aryl)thienylpyrroles (1) and benzothiazolyl diazonium salts (2–4) as coupling components. Their optical (linear and first hyperpolarizability), electrochemical, and thermal properties have been
