Abstract

NEW MATERIAL:A compound shown by the formula I [A is a group shown by the formula II (R is alkyl, alkoxy, nitro, dialkylamino, or halogen; n is 0W3), etc.].
EXAMPLE: A compound shown by the formula III.
USE: A photoconducting materials for sensitized substances for electrophotography.
PROCESS: A tetrazonium salt (e.g., tetrazonium difluoroborate, etc.) shown by the formula IV (X is an anionic functional group) is reacted with a compound (e.g., 2-hydroxyl-3-naphtoic acid anilide, etc.) shown by the formula V as a coupling component in an organic solvent, e.g., N,N-dimethylformamide, etc. In the operation, an alkali aqueous solution, e.g., an aqueous solution of sodium acetate, etc. at -10W10°C is added dropwise in the reaction, to give a compound shown by the formula I. The compound shown by the formula IV as a starting material is obtained by reducing 1,4-bis(3-nitrostyryl)benzene, followed by diazotization.
