    摘要： Provided are a donor-acceptor type compound having a novel structure and its use.
    An enamine compound represented by general formula (1)

    (in the formula:
    R 1 represents an electron-withdrawing group;
    A represents a divalent aromatic hydrocarbon group which may contain a substituent, a divalent aromatic heterocyclic group which may contain a substituent or a divalent unsaturated aliphatic hydrocarbon group which may contain a substituent;
    R 2 represents a hydrogen atom or a hydrocarbon group which may contain a substituent;
    R 3 and R 4 are the same or different from each other and represent an aromatic hydrocarbon group which may contain a substituent or an aromatic heterocyclic group which may contain a substituent, or R 3 and R 4 together form an optionally substituted bicyclic aromatic heterocyclic group containing two or more nitrogen atoms or a nitrogen atom and an oxygen atom or a sulfur atom, or a tricyclic aromatic heterocyclic group which may contain a substituent; and
    R 2 and A, or R 2 and R 3 may together form a cyclic structure).
