We present electrochemical and spectral properties of symmetric monomers 1,3,5-tris(aryl)benzenes and 2,4,6-tris(aryl)-1-phenols and their polymers These compounds contain thienyl. furyl or EDOT moieties attached to central benzene or phenol ring at the meta-position, synthesized by a Stille cross-coupling procedure All monomers are electroactive and undergo electropolymerization cleating thin films on an electrode surface. Polymers with meta-linkages wet e obtained by electrochemical oxidation Detailed cyclic voltammetry and in situ UV-vis spectroelectrochemistry show that polymers with hydroxy groups exhibit higher conductivity and better stability than with benzene Cole Interesting and different behavior occurs for 2,4,6-tris(2-thienyl)-1-phenol. for which the characteristic, sharp. redox peak is observed (C) 2010 Elsevier Ltd All rights reserved
