Polycyclic aromatic compound and light emitting layer-forming composition

A compound represented by the following general formula (A-1)

• in general formula (A-1),
• R1 to R11 each independently represent a hydrogen atom, an aryl, a heteroaryl, a diarylamino, a diheteroarylamino, an arylheteroarylamino, or an aryloxy, while at least one hydrogen atom in these may be further substituted by an aryl, a heteroaryl, or a diarylamino,
• adjacent groups among R1 to R11 may be bonded to each other to form an aryl ring or a heteroaryl ring together with ring a, ring b, or ring c, at least one hydrogen atom in the ring thus formed may be substituted by an aryl, a heteroaryl, a diarylamino, a diheteroarylamino, an arylheteroarylamino, or an aryloxy, at least one hydrogen atom in these may be further substituted by an aryl, a heteroaryl, or a diarylamino,
• at least one hydrogen atom in a compound represented by the above formula (A-1) is substituted by a group represented by the following general formula (FG-1), a group represented by the following general formula (FG-2), or an alkyl having 7 to 24 carbon atoms, at least one hydrogen atom in a compound represented by the above formula (A-1) may be further substituted by a halogen atom or a deuterium atom,
• any —CH2— in the alkyl may be substituted by —O— or —Si(CH3)2—, any —CH2— excluding —CH2-directly bonded to the compound represented by the above formula (A-1) in the alkyl may be substituted by an arylene having 6 to 24 carbon atoms, and any hydrogen atom in the alkyl may be substituted by a fluorine atom
• in general formula (FG-1),
• R's each independently represent a fluorine atom, a trimethylsilyl, a trifluoromethyl, an alkyl having 1 to 24 carbon atoms, or a cycloalkyl having 3 to 24 carbon atoms, any —CH2-in the alkyl may be substituted by —O—, any —CH2— excluding —CH2-directly bonded to a phenyl or a phenylene in the alkyl may be substituted by an arylene having 6 to 24 carbon atoms, at least one hydrogen atom in the cycloalkyl may be substituted by an alkyl having 1 to 24 carbon atoms or an aryl having 6 to 12 carbon atoms,
• when two adjacent R's each represent an alkyl or a cycloalkyl, these R's may be bonded to each other to form a ring,
• m's each independently represent an integer of 0 to 4,
• n's each independently represent an integer of 0 to 5, and
• p's each independently represent an integer of 1 to 5
