Electroluminescent device

An electroluminescent device comprising a anode and a cathode and at least one organic compound layer sandwiched therebetween, at least one organic compound layer being composed of an organic compound of the general formula (I):

• ##STR10## wherein A.sup.1 and A.sup.2 each represents:
• (a) an alkyl group;
• (b) an alkyl group substituted with a hydroxy group, cyano group, (C.sub.1 -C.sub.10) alkoxy group, phenyl group, halogen atom, or phenyl group substituted with (C.sub.1 -C.sub.12) alkyl group or (C.sub.1 -C.sub.12) alkoxy group;
• (c) an aryl group;
• or
• (d) an aryl group substituted with a halogen atom, trifluoromethyl group, cyano group, nitro group, a substituted or unsubstituted (C.sub.1 -C.sub.20) alkyl group, a substituted or unsubstituted (C.sub.1 -C.sub.20) alkoxy group, a substituted or unsubstituted (C.sub.1 -C.sub.20) alkylthio group, a substituted or unsubstituted aryloxy group;
• ##STR11## wherein R.sup.2 and R.sup.3 represent independently a hydrogen atom, a substituted or unsubstituted (C.sub.1 -C.sub.20) alkyl group, an aryl group or an acyl group, or join together with a carbon atom on an aryl group or nitrogen atom;
• a --COOR.sup.4 group wherein R.sup.4 represents a substituted or unsubstituted (C.sub.1 -C.sub.20) alkyl group or a substituted or unsubstituted aryl group, ##STR12## wherein R.sup.2, R.sup.3 and R.sup.4 represent the same meaning defined-above, provided that R.sup.2 and R.sup.3 do not join with a carbon atom on the aryl group;
• or an alkylenedioxy group, and A.sup.1 and A.sup.2 may be identical to or difference from each other;
• Ar represents a substituted or unsubstituted pyrenyl group;
• and n represents 1 or 2.
