Quinomethane compounds having a structure represented by the general formula (1):
1
wherein R
1
to R
4
and R
9
to R
12
are the same or different and each represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, a cyclic alkyl group, an aryl group, or an alkoxy group having 1 to 6 carbon atoms; R
5
and R
6
are the same or different and each represents an alkyl group having 1 to 12 carbon atoms, an aryl group, or a heterocyclic group; R
7
and R
8
each represents a hydrogen atom; and optional substituents are each a halogen atom, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an aryl group, or a heterocyclic group. Since these compounds transport electrons efficiently, they are useful in electrophotographic photoreceptors and/or organic electroluminescence applications.
具有通式(1)所表示的结构的喹诺
甲烷化合物:1其中R1至R4和R9至R12相同或不同,每个表示氢原子,具有1至12个碳原子的烷基,环状烷基,芳基或具有1至6个碳原子的烷氧基;R5和R6相同或不同,每个表示具有1至12个碳原子的烷基,芳基或杂环基;R7和R8各表示氢原子;可选取代基分别为卤原子,具有1至6个碳原子的烷基,具有1至6个碳原子的烷氧基,芳基或杂环基。由于这些化合物可以有效地输运电子,因此它们在电子照相感光鼓和/或有机电致发光应用中很有用。
