NOVELTY - An organic photoelectric transducer has a pair of electrode with at least one being transparent or semi-transparent, and a light-active layer and a functional layer between the electrodes. The light-active layer contains an electron donor and an electron-accepting compound. The functional layer contains a crosslinked-polymer compound obtained by crosslinking high molecular compound having nitrogen-containing structure (1).    USE - Organic photoelectric transducer is used for image sensor (claimed). Can also be used for organic thin film solar cell.    ADVANTAGE - The organic photoelectric transducer has high voltage during photoelectric conversion.    DETAILED DESCRIPTION - An organic photoelectric transducer has a pair of electrode with at least one being transparent or semi-transparent, and a light-active layer and a functional layer between the electrodes. The light-active layer contains an electron donor and an electron-accepting compound. The functional layer contains a crosslinked-polymer compound obtained by crosslinking high molecular compound having nitrogen-containing structure of formula: -(Ar1-(N(-X)-Ar2)m)- (1).    Ar1,Ar2=optionally substituted bivalent aromatic group, where the atom in Ar1 and the atom in Ar2 may bond together through single bond or bivalent group;    m=1 or more;    X=group of formula (2), or arylene containing substituent chosen from azido, di(hydrocarbyl)amino, hydroxy, acrylic acid alkylester residue, methacrylic acid alkylester residue, ethenyl, ethenyloxy, perfluoroethenyloxy, ethynyl, maleimide residue, nadimide residue, trialkylsiloxy, and trialkylsilyl, and the hydrogen atom in group of formula (2) and arylene may optionally substituted by halo, preferably group of formula (2);    R1-R3=H, halo, hydrocarbyl, halohydrocarbyl, or halocarbyl;and    R4=single bond, hydrocarbylene, halohydrocarbylene, or halocarbylene.    An INDEPENDENT CLAIM is included for manufacture of the organic photoelectric transducer, which involves forming functional layer containing high molecular compound having nitrogen-containing structure on one electrode, crosslinking the high molecular compound by heat or light, and forming light-active layer on the functional layer.
