Hayashi et al. have successfully developed a highly regioselective Pd/C-catalysed direct arylation toward thiophene-based π-conjugated polymers.
Pd/C heterogeneous catalysts were used in the direct arylation polycondensation of thiophenes. The efficient and highly regioselective polycondensation of thiophene monomers was achieved under phosphine-free conditions to give linear π-conjugated alternating copolymers with high molecular weight in high yield.
