An array of 1,3‐diarylbenzo[ c ]thiophenes have been synthesized by the ring‐opening of lactones followed by thionation using Lawesson's reagent with concurrent intramolecular cyclization. Photophysical studies of the various benzo[ c ]thiophene analogues are presented. The results of a cyclic voltammetric investigation of the benzo[ c ]thiophenes are also reported.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
