Abstract

In the general formula [1], R1 to R12 are each independently selected from the group consisting of a hydrogen atom and a substituent. Symbol A is selected from the group consisting of a divalent residue of naphthalene, phenanthrene, fluorene, benzofluorene, dibenzofluorene or spirofluorene, and a heteroarylene group having 4 to 12 carbon atoms. Symbol B is selected from the group consisting of an arylene group having 6 to 25 carbon atoms and a heteroarylene group having 4 to 12 carbon atoms. Symbol n is an integer of 0 to 3.

First claim

What is claimed is:

1 . An organic compound represented by the following general formula [1]:

wherein R 1 to R 12 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, an alkyl group, an aryl group having 6 to 18 carbon atoms, and a heteroaryl group having 3 to 15 carbon atoms; the alkyl group may have a halogen atom as a substituent; and the aryl group having 6 to 18 carbon atoms and/or the heteroaryl group having 3 to 15 carbon atoms may have a halogen atom, a cyano group, an alkyl group and/or an alkoxy group, as a substituent;
wherein A is selected from the group consisting of a divalent residue of naphthalene, phenanthrene, fluorene, benzofluorene, dibenzofluorene or spirofluorene, and a heteroarylene group having 4 to 12 carbon atoms; and A may have an alkyl group as a substituent;
wherein B is selected from the group consisting of an arylene group having 6 to 25 carbon atoms and a heteroarylene group having 4 to 12 carbon atoms; and B may have an alkyl group as a substituent; and
wherein n is an integer of 0 to 3, and when n is 2 or larger, the respective B's may be the same as or different from each other.

2 . The organic compound according to claim 1 , wherein A is a divalent residue of naphthalene, phenanthrene, fluorene, benzofluorene, dibenzofluorene or spirofluorene, and B is an arylene group having 6 to 25 carbon atoms.
