[Problems] To provide a novel compound which has a high carrier mobility and is useful as a charge-transporting agent that is not only capable of stably forming a photosensitive layer without precipitating crystals or forming pinholes at the time of forming the photosensitive layer but is also capable of forming an organic photosensitive material for electrophotography that has a high sensitivity and a low residual potential.
[Means for Solution] A diphenylnaphthylamine derivative represented by the following general formula (1),
wherein R1 to R3 are alkyl groups, k is an integer of 0 to 3, j is an integer of 0 to 4, 1 is an integer of 0 to 6, and X1 and X2 are hydrocarbon groups having at least one ethylenically unsaturated bond.
[问题]提供一种新型化合物,它具有高载流子迁移率,可用作电荷传输剂,不仅能够稳定地形成感光层,而且在形成感光层时不会析出晶体或形成针孔,还能够形成高灵敏度和低残留电位的电致发光用有机感光材料。
[解决方法]由以下通式(1)代表的二苯基萘胺衍生物、
其中 R1 至 R3 为烷基,k 为 0 至 3 的整数,j 为 0 至 4 的整数,1 为 0 至 6 的整数,X1 和 X2 为至少具有一个乙烯不饱和键的烃基。
