  • Process for N-doping of polymers
    Patent number: 4565650
    Abstract: A process for N doping polyacetylene or polyphenylene polymers by contacting the polymer with a doping agent selected from at least one composition selected from organolithium or the alkaline salts of carbanions or dicarbanions having a benzylic structure. The N doped polymers have electrochemical and photogalvanic applications.The invention is a novel process for doping polyacetylene or polyphenylene and the products obtained by the process. The process provides N doped polymers that can be used in electrochemical or photovoltaic applications.
