PURPOSE:To provide a new compound useful as an electric charge-generating material excellent in electric charge-generating efficiency. CONSTITUTION:The objective compound of formula I (R<1> and R<2> are each H or lower alkyl; Cp<1> and Cp<2> are each coupler residue). This compound can be obtained by reaction of a diazo compound of formula II (R<3> and R<4> are each halogen or BF4) with a coupler in a solvent (e.g. dimethylformamide) in the presence of a base (e.g. sodium acetate) at ca.20 deg.C for 3-10hr. The compound, when used as an electric charge-generating material, is highly sensitive in the visible ray region, thus providing high-performance electronic devices; furthermore, because of being easy to handle in terms of synthesis and high in the solubility to solvents, the compound can be used easily, being also usable for coloring pigments, organic photosensitizers, solar cells, or electronic devices such as photoelectric transfer elements and optical information memorizing elements. |
