Organic electroluminescence device and phenylenediamine derivative

A phenylenediamine derivative represented by the general formula (III)

• wherein Ar13 to Ar18 represent an aryl group having from 6 to 24 nucleus carbon atoms, which may be substituted with a hydrogen atom, an alkyl or an alkoxy group having from 1 to 6 carbon atom(s), an aryl group having from 6 to 24 nucleus carbon atoms, or a styryl group;
• X represents a linking group, which is a single bond, arylene having from 6 to 24 nucleus carbon atoms, alkylene having from 1 to 6 carbon atom(s), diphenylmethylene, an ether bond, a thioether bond, a substituted or unsubstituted vinyl bond, or an aromatic heterocyclic ring;
• R7 and R8 represent an alkyl group having from 1 to 6 carbon atom(s), an alkoxy group, or a hydrogen atom, which may be bonded to each other to form a substituted or unsubstituted saturated 5-membered ring or a saturated 6-membered ring, provided that at least one of Ar13 to Ar16 and X represents an aryl group containing a styryl group;
• or one of Ar15, Ar18 and a basic skeleton shown by the following chemical formula (1) contains a condensed aromatic ring, an aromatic heterocyclic ring or a substituted or unsubstituted vinyl group;
