Abstract
A process for preparing a conjugated polymer, which comprises polymerizing in a reaction mixture (a) an aromatic monomer having at least two boron derivative functional groups selected from the group consisting of boronic acid groups, boronic ester groups, and borane groups, and an aromatic monomer having at least two reactive halide functional groups, or (b) an aromatic monomer having one reactive halide functional group and one boron derivative functional group selected from the group consisting of boronic acid groups, boronic ester groups, and borane groups, an amount of a catalyst suitable for catalyzing the polymerization of the aromatic monomers, and a base in an amount sufficient to convert the boron derivative functional groups into boron anionic groups, characterized in that the reaction mixture further comprises a first solvent and a second solvent with which said first solvent is substantially immiscible and an emulsifier in an amount sufficient to form an emulsion of the reaction mixture.
