| titleOfInvention | Process for synthesizing sublimable linear phenylene based oligomers of controlled length |
| abstract | 1- l'électrolyse du catalyseur et sa réaction avec l'un des deux oligomères à un premier potentiel, 2- la réduction de l'espèce d'insertion obtenue selon l'étape 1, et sa réaction avec le second oligomère à un second potentiel inférieur au premier potentiel, et 3- la récupération de l'oligomère sublimable ainsi obtenu, les deux oligomères inférieurs utilisés étant des oligomères mono- ou dihalogénés, identiques ou différents. the present invention relates to a process for the preparation of phenyl-based sublimable oligomers, linear and of controlled length, by electrochemical coupling of two lower oligomers within a monocompartmented cell with three electrodes, in the presence of an organometallic catalyst , characterized in that it comprises: 1- the electrolysis of the catalyst and its reaction with one of the two oligomers at a first potential, 2- the reduction of the insertion species obtained according to step 1, and its reaction with the second oligomer at a second potential lower than the first potential, and 3- recovery of the sublimable oligomer thus obtained, the two lower oligomers used being mono- or dihalogenated oligomers, identical or different. n n n the present invention also relates to the sublimable phenylene-based oligomers obtained according to this process, and their applications in electronics and / or optics. |
