Abstract:
A nitrogen-containing aromatic heterocyclic derivative represented by the following formula, wherein X1 to X3 are a single bond, CRaRb, NRc, an oxygen atom or a sulfur atom, and when all of X1 to X3 is a single bond, at least one of Ara, Arb and Arc is an aryl group having 6 to 20 ring carbon atoms substituted with a heteroaryl group, an aryloxy group or a heteroaryloxy group, or a substituted or unsubstituted heteroaryl group having 5 to 20 ring atoms.
