A NOVEL PHENYLENE TYPED COMPOUND AND THE ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE USING IT

摘要

An asymmetric phenylene group compound is provided to ensure excellent blue light emitting property, hole transport property and electron transport property, and to perform high efficiency light emitting when applied to the organic light-emitting device. An asymmetric phenylene group compound has a structure represented by chemical formula 1. In chemical formula 1, Ar1 and Ar2 are substituted or unsubstituted C6~C40 aryl group or heteroaryl group; and R1, R2, R3, R4 and R5 are independently amino group, nitrile group, nitro group, halogen group, C1~C40 alkyl group, C1~C40 alkoxy group, C3~C40 cycloalkyl group, C3~C40 heterocycloalkyl group, C6~C40 substituted or unsubstituted aryl group or C6~C40 substituted or unsubstituted heteroaryl group. The phenylene group compound has the asymmetric structure around Ar1.
