An organic electron transport material, which includes a phosphine oxide derivative represented by the following Formula (1):
R1 represents an atomic group which has either or both of one or more aryl groups and one or more heteroaryl groups and which may have one or more phosphine oxide group, and R2 to R9 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 C1-C12 linear or branched alkyl group, a linear or branched fluoroalkyl group, an aryl group, a substituted aryl group, a heteroaryl group, and a substituted heteroaryl 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,该原子团具有一个或多个芳基和一个或多个杂芳基中的一个或两个,并可具有一个或多个氧化膦基团;R2 至 R9 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、C1-C12 直链或支链烷基、直链或支链氟烷基、芳基、取代的芳基、杂芳基和取代的杂芳基组成的组。
