CONJUGATED POLYMER PREPARATION VIA SUZUKI-COUPLING IN EMULSION

摘要

A process for preparing a conjugated polymer,which comprises polymerising in a reaction mixture(a)an aromatic monomer having at least two boron derivative functional groups selected from a boronic acid group,a boronic ester group and a borane group,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 a boronic acid group,a boronic ester group and a borane group;an amount of a catalyst suitable for catalysing the polymerisation of the aromatic monomers;and a base in an amount sufficient to convert the boron derivative functional groups into boron anionic groups,characterised in that said 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 said reaction mixture.
