Abstract
A method for preparing polymers by direct heteroarylation or arylation polycondensation is described herein. The method includes preparing a reaction mixture including at least a monomer to be polymerized, a catalyst and a ligand; heating the reaction mixture, and, optionally, end-capping the reaction mixture.
