Abstract:
The present invention discloses a new indenotriphenylene derivatives and an organic light emitting device using the derivative. The organic light emitting device employing the new indenotriphenylene derivative as host material can lower driving voltage, prolong half-lifetime, increasing efficiency. The new indenotriphenylene derivative is represented by the following formula(A): According to formula(A), A1, A2 are substituted or unsubstituted aromatic ring systems with one to five rings and independently selected from the group consisting of a phenyl group, a naphthyl group, an anthracenyl group, a pyrenyl group, a chrysenyl group and a 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, an 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 and a substituted or unsubstituted heteroaryl group having 6 to 30 carbon atoms. X is selected from carbon atom or nitrogen atom.
Abstract:
The present invention provides an indeno[1,2-b]phenanthrene compound having suppressed hole transport ability. The indeno[1,2-b]phenanthrene compound represented by the general formula [1] described in claim 1 is provided. In the formula [1], R1 and R2 each represent a hydrogen atom or an alkyl group. X1 and X2 each represent a substituent selected from the group consisting of a hydrogen atom, an alkyl group, a methoxy group, and a cyano group. A1 represents a monovalent or a divalent aromatic hydrocarbon group. A2 represents a monovalent or a divalent aromatic hydrocarbon group or a monovalent or a divalent heteroaromatic group. n represents an integer of 0 to 4. When n is 2 or more, a plurality of A2 may be identical to or different from each other.
