通过取代芳醛与1,1-二苯肼反应,合成了2-甲基-4-(N,N-二苄基)氨基苯甲醛-1,1-二苯基腙(a)、2-甲基-4-(N-乙基-N-苄基)氨基苯甲醛-1,1-二苯基腙(b)、4-(N-乙基-N-苄基)氨基苯甲醛-1,1-二苯基腙(c)和4-(N,N-二对甲基苯基)氨基苯甲醛-1,1-二苯基腙(d),其合成收率为82%～98%.通过紫外光谱、红外光谱、质谱及元素分析等测试手段对合成产物的组成和结构进行了分析鉴定,HPLC纯度均大于99.4%.用合成的化合物作为空穴传输材料制成功能分离型有机光导器件,测试数据表明,腙a和腙d具有优良的空穴传输特性.

Synthetic methods of tri-substituted aminobenzaldehyde hydrazones, used as hole transport materials （ HTM ）, were studied. 2-Methyl-4-dibenzylaminobenzaldehyde-1,1 -diphenydrazone, 2-methyl-4- （N-ethyl-N-benzyl） arninobenzaldehyde-1,1 -diphenydrazone, 4-（ N-ethyl-N-benzyl ） arninobenzaldehyde-1,1 - diphenydrazone and 4-his （p-methylphenyl） aminobenzaldehyde-1,1-diphenydrazone were prepared by the reaction of substituted aromatic aldehydes with 1,1-diphenylhydrazine, and their yields were from 82% to 98%. The compositions and structures of the products were characterized by means of UV, IR, MS and elemental analysis. The HPLC purity is higher than 99.4%. The double-layer organic photoconductors were fabricated with the above four compounds as HTM. The tested results of the photoconductors show that hydrazone a and hydrazone d have excellent photographic performance.
