Compound, organic electroluminescent element material, organic electroluminescent element, and electronic apparatus

Compounds represented by formula (1) make possible the emission of single peak light that is bluer (shorter wavelength), has a more narrow half width (greater color purity) and does not have second peaks. (in formula (1), Ar represents a substituted or unsubstituted 1-20 carbon alkyl group, a substituted or unsubstituted ring-forming 6-30 carbon aryl group, or a substituted or unsubstituted ring-forming 5-30 atom nitrogen-containing heteroaryl group; L 1 and L 2 each independently represent a single bond, a substituted or unsubstituted ring-forming 6-30 carbon arylene group, a substituted or unsubstituted ring-forming 5-30 atom heteroarylene group, or a substituted or unsubstituted divalent connecting group in which two to four groups selected from ring-forming 6-30 carbon arylene groups and ring-forming 5-30 atom heteroarylene groups are bonded via single bonds; A represents a monovalent group represented by formula (2); and B represents a monovalent group represented by formula (5). (R 1 -R 10 and R 21 -R 30 are defined as in the Description.))
