Polycyclic aromatic compound

A polycyclic aromatic compound represented by Formula (1):

• wherein:
• A11 ring, A21 ring, A31 ring, B11 ring, B21 ring, C11 ring, and C31 ring are each independently an aryl ring or a heteroaryl ring, and at least one hydrogen in these rings may be replaced;
• Y11, Y21, Y31 are each independently B, P, P═O, P═S, Al, Ga, As, Si—R, or Ge—R, and R in the above Si—R and Ge—R is an aryl, an alkyl, or a cycloalkyl;
• X11, X12, X21, X22, X31, X32 are each independently >O, >N—R, >C(—R)2, >S, or >Se,
• wherein R in the above >N—R is an aryl which may be substituted, a heteroaryl which may be substituted, an alkyl which may be substituted, or a cycloalkyl which may be substituted, R in the above >C(—R)2 is hydrogen, an aryl which may be substituted, an alkyl which may be substituted, or a cycloalkyl which may be substituted, and R in the above >N—R and/or in the above >C(—R)2 may be bonded to A11 ring, A21 ring, A31 ring, B11 ring, B21 ring, C11 ring, and/or C31 ring by a linking group or a single bond;
• and
• at least one hydrogen in the compound represented by Formula (1) may be replaced with deuterium, cyano, or a halogen.
