Claim 0:
1. 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.
