Naphthalenetetracarboxylic acid diimide derivatives represented by the following general formula,
wherein R is a hydrogen atom, an alkyl group, an alkoxyl group or a halogen atom, R1 and R2 are different from each other and may be a substituted or unsubstituted alkyl group, alkoxyl group or an aryl group, respectively, and R3 is a hydrogen atom, a substituted or unsubstituted alkyl group, an alkoxyl group or an aryl group.
The derivatives exhibit excellent solubility in an organic solvent, excellent compatibility with a resin binder and excellent photosensitivity, and are very useful as an electron transporting agent for the electrophotosensitive material.
由以下通式代表的萘四甲酸二亚胺衍生物、
其中 R 是氢原子、烷基、烷氧基或卤素原子,R1 和 R2 互不相同,可以分别是取代或未取代的烷基、烷氧基或芳基,R3 是氢原子、取代或未取代的烷基、烷氧基或芳基。
这些衍生物在有机溶剂中的溶解性极佳,与树脂粘合剂的相容性极佳,光敏性极佳,作为电致发光材料的电子传输剂非常有用。
