Compound, material for organic electroluminescent elements, organic electroluminescent element, and electronic device

A compound of formula (1):

• wherein
• R1 and R2 each are independently a hydrogen atom or a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, in which R1 and R2 are not bonded to each other;
• *p, *q, *r, and *s each represent a carbon atom;
• *b is a bond bonded to one of the carbon atoms represented by *p, *q, *r, and *s;
• R15 or R17 is a single bond bonded to *a, and remaining R11 to R18, that are not the single bond bonded to *a, are each are independently selected from a hydrogen atom, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, and a cyano group;
• L is a substituted or unsubstituted arylene group having 6 to 30 ring carbon atoms;
• and
• R31 to R35 each are independently a hydrogen atom or a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, and no combination of two adjacent substituents selected from R31 to R35 is bonded to each other to form a ring.
