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.
Claims30
A method for preparing a polymer comprising:
- (a) treating one or more monomers, one or more catalysts and one or more ligands under conditions for the direct arylation or heteroarylation of the at least one monomer to provide the polymer;
- and
- (b) isolating the polymer.
A polymer comprising repeating units of the Formulae (V), (VI) or (VII):
- -[A1-A2]- (V);
- -[A3]- (VI);
- or
- -[A3-A4]- (VII),
- wherein
- A1, A2, A3 and A4 are independently selected from aryl and heteroaryl;
- and the polymers were prepared using direct arylation or heteroarylation conditions.
