Disclosed is a method for production of a conjugated polymer. The method comprises the step of (A) contacting an aromatic monomer having at least two boron-containing functional groups with an aromatic monomer having at least two reactive functional group or (B) contacting aromatic monomers each having at least one boron-containing functional group and at least one reactive functional group with each other, both in an ether solvent in the presence of a palladium catalyst having a phosphine compound coordinated to palladium, cesium carbonate and 1 to 100 moles of water relative to 1 mole of the boron-containing functional group in the aromatic monomer.

La présente invention concerne un procédé de production d'un polymère conjugué. Le procédé comprend l'étape consistant à (A) mettre en contact un monomère aromatique ayant au moins deux groupes fonctionnels contenant un atome de bore avec un monomère aromatique ayant au moins deux groupes fonctionnels réactifs ou (B) mettre en contact des monomères aromatiques ayant chacun au moins un groupe fonctionnel contenant un atome de bore et au moins un groupe fonctionnel réactif, tous les deux dans un solvant éther en présence d'un catalyseur à base de palladium ayant un composé phosphine coordiné au palladium, du carbonate de césium et de 1 à 100 moles d'eau sur la base d'une mole du groupe fonctionnel contenant un atome de bore dans le monomère aromatique.
