1. A organic compound with a general formula(I) as following:m represent an integer of 0 to 10, n represent an integer of 0 to 2. X is a divalent bridge selected from the atom or group consisting from O, S, C(R5)2, N(R5), Si(R5)2. Ar represent a hydrogen atom, a halide, a substituted or unsubstituted arylamine group, a substituted or unsubstituted aryl group system having 5 to 50 aromatic ring atoms, a substituted or unsubstituted heteroaryl ring system having 5 to 50 aromatic ring atoms and each aromatic ring to form a mono or polycyclic ring system. R1 to R5 are identical or different. R1 to R5 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.
