| 摘要 |
NEW MATERIAL:A compound expressed by formula I (Z is benzene ring, naphthalene ring or carbazole ring; R is H, halogen, lower alkyl, lower alkoxyl or nitro; n is 1-3). EXAMPLE:1,12-Bis[4-( 2-hydroxy-3-phenylcarbamoylnaphthyl-1-azo )phenyl]-1,3,5, 7,9,11-dodecahexaene. USE:Useful as an electrophotographic photosensitive material for high-speed copiers and laser printers, particularly organic semiconductor used in laminated type photosensitive materials. PREPARATION:A tetrazolinium salt expressed by formula II (X is anionic functional group) is subjected to coupling reaction with a coupler expressed by formula III. |
