Cross-coupling polycondensation via C–O or C–N bond cleavage

Abstract

π-Conjugated polymers are useful commodities as they are used in the fabrication of organic photovoltaic devices, light-emitting diodes and field effect transistors. Here the authors describe the polycondensation of bifunctional aryl ethers or aryl ammonium salts with aromatic dimetallic compounds through cleavage of inert C–O/C–N bonds.
