NEW MATERIAL:A compound shown by the formula I (R<1> is H, lower alkyl, or phenyl; R<2> is lower alkyl, lower alkoxyl, halogen, or cyano; Ar is phenyl, or styryl; n is 1, or 2). EXAMPLE:4-[N-(4-Methylphenyl)-N-phenyl]aminostilbene. USE:Useful as a photoconductive material in a sensitized material for electrophotography. Being sensitized optically or chemically with a sensitizer such as dye, Lewis acid, etc. Useful as an electron transfer substance in a sensitized material of function separation type having an organic or inorganic pigment as the electron transfer substance. PREPARATION:A phenyl derivative shown by the formula II (R is lower alkyl) is reacted with an aldehyde compound shown by the formula III in the presence of a basic catalyst (e.g., potassium-t-butoxide, caustic soda, etc.) in a solvent such as N,N-dimethylformamide, etc. at room temperature -100 deg.C, to give a compound shown by the formula I .
