PROCESS FOR PREPARING THIENOÝ3,4-B¨PYRAZINE COPOLYMERS, THIENOÝ3,4-B¨-PYRAZINE COPOLYMERS PREPARED BY THIS PROCESS, AND THEIR USE

New thieno[3,4-b]pyrazine copolymers are prepared by reacting 5,7-functionalized thieno[3,4-b]pyrazines with substituted aromatics in the presence of solvents, bases and polymerization catalysts, the copolymers thus prepared being employed preferably in the production of photovoltaic cells.
