1. A phenanthro[9,10-b]tetraphenylene derivative with a general formula(I) as following:Wherein L1, L2 represent a single bond, a substituted or unsubstituted arylene group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted heterarylene group having 3 to 30 ring carbon atoms. m represent an integer of 0 to 8. p represent an integer of 0 to 3, q represent an integer of 0 to 9. R1 to R3 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 3 to 30 carbon atoms. Ar1 and Ar2 independently represent a substituted or unsubstituted arylamine, a substituted or unsubstituted heteroarylamine, a substituted or unsubstituted aryl group having 6 to 50 carbon atoms, a substituted or unsubstituted heteroaryl group having 3 to 50 carbon atoms. wherein at least one of Ar1 and Ar2 represent a substituted or unsubstituted diphenylamine group, a substituted or unsubstituted N-phenylnaphthalene-2-amine group, a substituted or unsubstituted dibiphenyl-4-ylamine group, a substituted or unsubstituted N-phenyldibenzo[b,d]furan-4-amine group, a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted phenanthrenyl group, a substituted or unsubstituted pyrenyl group, a substituted or unsubstituted chrysenyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted perylenyl group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted biscarbazolyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted triazinyl group, a substituted or unsubstituted diazinyl group, a substituted or unsubstituted phenanthroline group, a substituted or unsubstituted dihydroacridine group, a substituted or unsubstituted phenothiazine group, a substituted or unsubstituted phenoxazine group, a substituted or unsubstituted dihydrophenazine group and the substituent for Ar1, Ar2 each have the same definition as R1. |
