Outline of Final Research Achievements

Facile synthesis of practical n-type organic polymer semiconductor accelerates development of organic electronics. Towards development of such kind of materials, a series of fullerene-diamine adduct and their solutions with polar solvents were obtained. Thin-films from these polar solutions of the fullerene-diamine adduct works as organic electronic materials, which were confirmed by organic thin-film solar cell application. In the case of use of water soluble or dispersible fullerene-host complexes, similar adduct products were obtained. These products function as organic electronic materials, which is suggested via electronic and photovoltaic applications.
