Abstract:
1. Process for preparing a regioregular poly(3-substituted thiophene) or poly(3-substituted selenophene) by a) reacting a 3-substituted thiophene or 3-substituted selenophene each having leaving groups in 2- and 5-position (“educt”) with magnesium or reactive zinc or an organomagnesium halide, b) reacting a Ni(0) catalyst and a bidentate ligand with an aromatic monomer or oligomer having one or more leaving groups (“activator”), c) bringing the reaction mixtures resulting from step a) and b) into contact with each other, and optionally agitating and/or heating the resulting mixture, thereby starting a polymerisation reaction, d) optionally adding a reagent that stops the polymerisation reaction, and optionally recovering the polymer from the reaction mixture.
