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 A
1
, A
2
are substituted or unsubstituted fused ring hydrocarbon units with one to five rings. Preferably A
1
, A
2
are phenyl group, naphthyl group, anthracenyl group, pyrenyl group, chrysenyl group. Perylenyl group. R
1
to R
4
are identical or different. R
1
to R
4
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.
