A novel heterocyclic moiety based on thiazolo[4.5-d]thiazole was prepared via a six-step synthesis from butane-2,3-dione. This thiazolothiazole compound was further derivatized to afford either neutral conjugated condensation products or analogous N-alkyl salts. The obtained derivatives represent dipolar structures expressed as A-pi-D (push-pull compounds) as well as quadrupolar D-pi-A-pi-D structures. Both types of compound show intramolecular charge transfer and therefore could be suitable for nonlinear optical applications. (C) 2010 Elsevier Ltd. All rights reserved.
