Organic Compound, Charge-Transporting Material, and Organic Electroluminescent Element

摘要

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 Cz¹ and Cz² 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 Cz¹ and Cz² with each other; and Q represents a direct bond connecting to "G" in following Formula (II): wherein Ring B¹ 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 B¹; G represents an aromatic hydrocarbon group when G does not connect to Q; and "m" represents an integer of from 3 to 5.
