Star-shaped triazine-thiophene conjugated systems

Star-shaped molecules consisting of short-chain oligothiophenes attached onto an electron acceptor triazine core have been synthesized. Results of the analysis of the electronic properties of these compounds by UV-vis spectroscopy and cyclic voltammetry are used to discuss the impact of the electron-withdrawing node on the properties of the compounds. The electrochemical oxidation of some of these systems into the corresponding electroactive polymers is briefly discussed. (C) 2009 Published by Elsevier Ltd.
