Abstract

An organic light-emitting material having the structure of formula (I) or (II) as described below and an organic light-emitting device (OLED) are disclosed. The OLED adopts the compound containing fluoranthene group as the electron transport material possessing good electron transport and injection ability. The material also enhances the luminous efficiency and lifetime of the device because of its excellent thermal stability and film-forming properties. At the same time, the high triplet energy and excellent electron transport capacity of the material containing fluoranthene group make it suitable to be used as the host for phosphorescent devices, increasing the number of electrons in the light-emitting layer and the efficiency of the device.
