Abstract: A compound represented by the formula (12X). In the formula (12X), Py1 and Py2 each independently represent a substituted or unsubstituted 1-pyrenyl group, L1 and L2 each independently represent a substituted or unsubstituted phenylene group or a substituted or unsubstituted naphthylene group. When L1 and L2 each independently represent a substituted or unsubstituted phenylene group, -L1-L2- in the formula (12X) represents a group represented by one of the formulae (13-1) to (13-6), (10-1), (20-1), and (30-1). When L1 and L2 each independently represent a substituted or unsubstituted naphthylene group, a bonding position of the naphthylene group in L1 is different from a bonding position of the naphthylene group in L2.
