PURPOSE: To obtain the subject new compound capable of being charged into a suitable electric potential and little in discharge in a dark place, capable of rapidly discharging the electric potential under the irradiation of light, useful as a photoconductive raw material, especially an electric charge-transfer substance, and suitable for the photosensitive layers of electronic photographic sensitizers. CONSTITUTION: A compound of formula I [R is a (substituted) 1-8C alkyl; X is a 1-6C alkyl, a halogen, a 1-6C alkoxycarbonyl, cyano, nitro; (n) is 0-3]. For example, 1-(1,4-diethoxycarbonyl-2,3-benzofluorenylideneamino)-2-isopropylbenzene. The compound of formula I is obtained by reacting a compound of formula II with a compound of formula III in the presence of an acidic catalyst such as (trifluoro)acetic acid or titanium tetrachloride. |
