The effects of binding ligand variation on the externally initiated Ni catalyzed polymerization of P3HT were investigated using a novel methodology allowing facile screening of ligands. P3HT was synthesized with >80% initiator incorporation for both mono- and bidentate phosphine ligands. Variation of the initiating aryl group demonstrated vastly superior results for o-tolyl over p-tolyl substituents.
