2. The polycyclic aromatic compound according to claim 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 with a substituted or unsubstituted aryl, a substituted or unsubstituted heteroaryl, a substituted or unsubstituted diarylamino (the two aryls may be bonded to each other by a single bond or a linking group), a substituted or unsubstituted diheteroarylamino, a substituted or unsubstituted arylheteroarylamino, a substituted or unsubstituted diarylboryl, a substituted or unsubstituted alkyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aryloxy, a substituted silyl, or SF5;
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 by an alkyl or a cycloalkyl, a heteroaryl which may be substituted by an alkyl or a cycloalkyl, an alkyl, or a cycloalkyl, R in the above C(—R)2 is hydrogen, an alkyl, a cycloalkyl, or an aryl which may be substituted by an alkyl or a cycloalkyl, and R in the above N—R and/or 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 O, S, —C(—R)2—, —Si(—R)2— or a single bond, and R in the above —C(—R)2— and —Si(—R)2— is hydrogen, an alkyl or a cycloalkyl.
