Synthesis by Stille cross-coupling procedure and electrochemical properties of C3-symmetric oligoarylobenzenes
摘要:
A series of various C3-symmetric molecules were synthesized by Stille cross-coupling procedure. Monomers have been characterized by (1)H NMR, (13)C NMR. Received oligomers in the process of electropolymerization, containing thienyl, furyl, and EDOT groups provide good conductivity and show stability in common organic solvents such as CHCl(3), toluene, and CH(2)Cl(2) and exhibit thermal stability. Electrochemical results suggest that obtained materials can be successfully used in wide scale of organic-electronic devices such as organic light-emitting diodes (OLEDs), organic field-effect transitors (OFETs), and organic solar cells.

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
