Title (EN) IMPROVED PROCESS FOR SUBSTITUTED POLYTHIOPHENE POLYMERS
(FR) PROCESSUS AMELIORE DE POLYMERES POLYTHIOPHENES SUBSTITUES
Abstract:
(EN) An improved process for preparing regioregular substituted polythiophenes is described where a substituted thiophene having at least two leaving groups is treated with an organomagnesium halide followed by zinc chloride or bromide and the resulting reaction mixture in solution is polymerized with a Ni(II) catalyst.
(FR) La présente invention concerne un processus amélioré permettant de préparer des polithiophènes substitués, un thiophène substitué possédant au moins deux groupes vivants et étant traité avec un halogénure organomagnésium suivi par chlorure ou bromure de zinc et le mélange de réaction résultant dans une solution est polymérisé avec un catalyseur Ni(II).
