摘要：
A charge transporting material, a light emitting material and an organic electroluminescent device having high efficiency using a specified diazapentacene derivative represented by the following general formula (1): (in the general formula (1), R1 to R10 each represents independently a hydrogen atom, a halogen atom, an alkyl group of 1 to 6 carbon atoms, an alkoxy group, a substituted or not-substituted amino group, an aryl group or a heterocyclic group, in which the substituted or not-substituted aryl group or heterocyclic group, when they are adjacent with each other, may be of a structure condensed to each other, X1 and X2 each represents independently an oxygen atom or a sulfur atom, and Y1 and Y2 each represents independently a substituted or not-substituted alkyl group of 1 to 6 carbon atoms, an aryl group or a heterocyclic group).
