There are provided an organic having both excellent hole transporting
property and satisfactory electron transporting and showing excellent
durability against electric oxidation/reduction and a high triplet
excitation level, and a charge transporting material and an organic
electroluminescent device each using the organic compound. The organic
compound is represented by following Formula (I):
wherein Cz.sup.1 and Cz.sup.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.sup.1 and
Cz.sup.2 with each other; and Q represents a direct bond connecting to
"G" in following Formula (II):
wherein Ring B.sup.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; G represents a direct bond or an arbitrary linkage group
connecting to Q when G connects to Q; Gs connect to carbon atoms at the
ortho-position and the para-position with respect to nitrogen atom(s) in
Ring B.sup.1; G represents an aromatic hydrocarbon group when G does not
connect to Q; and "m" represents an integer of from 3 to 5.
