An organic compound is represented by following Formula (I): ##STR00001## wherein Cz.sup.1 and Cz.sup.2 may be the same as or different from each other and each represent a carbazolyl group; Q.sup.1 and Q.sup.2 may be the same as or different from each other and each represent a direct bond or an arbitrary linkage group; and Cz.sup.1, Cz.sup.2, Q.sup.1, Q.sup.2, Ring B.sup.1 and Ring B.sup.2 may each be substituted. The organic compound and charge transporting material show both excellent hole transporting ability and excellent electron transporting ability and have satisfactory durability against electric oxidation/reduction and a high triplet excitation level. An organic electroluminescent device using the organic compound emits light with a high efficiency and is highly stably driven.
