An organic electron transport material, which includes a phosphine oxide derivative represented by the following Formula (1):
R1 represents an atomic group which has one or more of either or both of aryl and heteroaryl groups and may have one or more phosphine oxide groups, R2 to R11 each independently represent an atom or an atomic group selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, a nitro group, a carboxyl group, a formyl group, a carbonyl group, an alkoxycarbonyl group, and a trifluoromethyl group.
一种有机电子传输材料,其中包括由下式(1)表示的氧化膦衍生物:
R1 代表一个原子团,该原子团具有芳基和杂芳基中的一个或多个,并可具有一个或多个氧化膦基团;R2 至 R11 各自独立地代表一个原子或原子团,该原子或原子团选自由氢原子、卤素原子、氰基、硝基、羧基、甲酰基、羰基、烷氧羰基和三氟甲基组成的组。
