ORGANIC LIGHT EMITTING DEVICE COMPRISING 9,10-DIHYDROACRIDINE DERIVATIVE

摘要

Provided is an organic light emitting device (OLED) comprising 9,10-dihydroacridine derivative represented by the following Formula (I):;;The 9,10-dihydroacridine derivative can be used as a hole transport material or an emission material of an organic light emitting device. With the aromaticity of the 9,10-dihydroacridine derivative, the OLED can have improved current efficiency and chromaticity.
