INDENOTRIPHENYLENE DERIVATIVES AND ORGANIC LIGHT EMITTING DEVICE USING THE SAME

The present invention discloses a new indenotriphenylene derivatives and organic light emitting device using the derivatives. The organic light emitting device employing new indenotriphenylene derivatives as host material can lower driving voltage, prolong half-lifetime, increasing efficiency. The new indenotriphenylene derivatives are represented by the following formula (A): Wherein A1, A2 are substituted or unsubstituted fused ring hydrocarbon units with one to five rings. Preferably A1, A2 are phenyl group, naphthyl group, anthracenyl group, pyrenyl group, chrysenyl group. Perylenyl group. R1 to R4 are identical or different. R1 to R4 are independently selected from the group consisting of a hydrogen atom, a halide, alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms, a substituted or unsubstituted heteroaryl group having 6 to 30 carbon atoms. X is selected from carbon atom or nitrogen atom.
