NOVELTY - A photoelectric-conversion material contains heterocyclic compound (1,2 or 3).    USE - For semiconductor electrode used for optoelectric transducer (both claimed) such as solar cell, and photosensor.    ADVANTAGE - The photoelectric-conversion material provides optoelectric transducer having excellent photoelectric transfer characteristics.    DETAILED DESCRIPTION - A photoelectric-conversion material contains heterocyclic compound of formulae (1,2 or 3).    R1-R3,R6-R8,R-11-R13 = hydrogen, optionally substituted (alkyl, aralkyl, alkenyl, alkoxy, alkylthio, di-substituted amino, halogen, aryl or heterocyclic ring);    R1+R2,R2+R3, R6+R7,R7+R8,R11+R12,R12+R13 = optionally together forms a cyclic structure;    R4 = coupling group which couples hetero five-membered ring and A1 ring, and optionally has a substituent;    R5,R10,R17 = hydrogen or optionally substituted alkyl;    X1,X4,X7,X8 = oxygen, sulfur or substituted amino;    X2,X3 = oxygen, sulfur, nitrogen, alkylene, substituted amino, carbonyl, sulfonyl or thiocarbonyl, optionally having a substituent;    A1 ring, C1 ring = aliphatic condensed ring, aromatic condensed ring or heterocyclic ring;    n1-n3 = 0-3;    R9 = coupling group which couples hetero five-membered ring and B1 ring, and optionally has a substituent;    X5 = hydrogen or optionally substituted aryl;    X6 = methine or substituted amino;    B1 = heterocyclic ring;    R14 = coupling group which couples hetero five-membered ring and C1 ring, and optionally has a substituent;    R15,R16 = hydrogen, alkyl, alkoxy, aryl, heterocyclic ring or halogen; and    X9 = substituted amino, oxygen, sulfur, carbonyl, dicyano methylene or bis(alkoxycarbonyl)methylene.    INDEPENDENT CLAIMS are also included for:    (1) semiconductor electrode comprising semiconductor layer formed on electroconductive substrate. A pigment containing heterocyclic compound(s) of formulae (1-3) is adsorbed to the surface of semiconductor layer; and    (2) optoelectric transducer using the semiconductor electrode.
