Patent ID: 8324403

Claim:
An organic compound represented by following Formula (I): wherein Cz 1 and Cz 2 each represent a carbazolyl group; Z represents a direct bond or an arbitrary linkage group enabling the conjugation of nitrogen atoms in the carbazole rings of Cz 1 and Cz 2 with each other; each of Cz 1 , Cz 2 , and Z may be substituted; Q represents a direct bond connecting to “G” in following Formula (II): wherein Ring B 1 represents a six-membered aromatic heterocyclic ring having “n” nitrogen atom(s) as hetero atom(s); “n” represents an integer of from 1 to 3; Gs connect to carbon atoms at an ortho position and a para position with respect to the nitrogen atom(s) in Ring B 1 ; G represents a direct bond or an arbitrary linkage group connecting to Q when G connects to Q; G represents an aromatic hydrocarbon group when G does not connect to Q; “m” represents an integer of from 3 to 5; plural Gs in one molecule may be the same as or different from one another; and Ring B 1 may have one or more substituents in addition to Gs, wherein said arbitrary linkage group, if present, represents -(Ph) p -, wherein Ph represents a phenylene group which may be substituted; and “p” represents an integer of from 1 to 8.
