Abstract:
An organic compound represented by the following general formula (1), (4) or (5): wherein X is fluorenone or a heterocyclic group, said heterocyclic group being selected from divalent moieties of compounds selected from the group consisting of carbazole, dibenzofuran, dibenzothiophene, oxazole, oxadiazole and thiadiazole; three groups among Ar1, Ar2, Ar3, and Ar4 are a substituted or unsubstituted fluorenyl group having one sp3 fluorene ring carbon, and the remainder is a substituted or unsubstituted aryl group; wherein X is fluorenone or a heterocyclic group, said heterocyclic group being selected from divalent moieties of compounds selected from the group consisting of carbazole, dibenzofuran, dibenzothiophene, oxazole, oxadiazole and thiadiazole; Ar1 and Ar2 are each a substituted or unsubstituted aryl group; R1, R2, R3 and R4 are each independently a hydrogen or halogen atom, or a substituted or unsubstituted alkyl, alkoxyl, or aryl group; and R5 and R6 are each independently a hydrogen or halogen atom, a nitro or cyano group, or a substituted or unsubstituted alkyl, alkoxyl, aryl, or carbonyl group; wherein X is fluorenone or a heterocyclic group, said heterocyclic group being selected from divalent moieties of compounds selected from the group consisting of carbazole, dibenzofuran, dibenzothiophene, oxazole, oxadiazole and thiadiazole; R7, R8, R9, R10, R11, R12, R13, and R14 are each independently a hydrogen or halogen atom, or a substituted or unsubstituted alkyl, alkoxyl, or aryl group; each of R15, R16, R17 and R18 is independently a hydrogen or halogen, nitro or cyano, or a substituted or unsubstituted alkyl, alkoxyl, aryl, amino or carbonyl group.
