摘要： A compound is represented by one of formulae (11) to (13). R1 to R4 each independently represent a group represented by a formula (1-1), a group represented by a formula (2-1), a group represented by a formula (2-2) or the like. At least one of R1 to R4 is the group represented by the formula (1-1) or the like. At least one of R1 to R4 is the group represented by the formula (2-1), (2-2) or the like. For instance, in the formula (1-1), R11 represents a substituent, and R101 to R110 each independently represent a hydrogen atom or a substituent. For instance, in the formulae (2-1) to (2-2), R161 to R168 and R171 to R180 each independently represent a hydrogen atom or a substituent. * each independently represents a bonding position to a carbon atom in a benzene ring in each of the formulae (11) to (13),

摘要： A compound is represented by one of formulae (11) to (13). R1 to R4 each independently represent a group represented by a formula (1-1) or the like, or a group represented by a formula (2-1), a group represented by a formula (2-2) or the like. At least one of R1 to R4 is the group represented by the formula (1-1) or the like. At least one of R1 to R4 is the group represented by the formula (2-1), (2-2) or the like. For instance, X1 represents an oxygen atom, a sulfur atom, or CR151R152, R101 to R110 and R151 and R152 each independently representing a hydrogen atom or a substituent. For instance, R161 to R168 and R171 and R180 each independently represent a hydrogen atom or a substituent. * each independently represents a bonding position to a carbon atom in a benzene ring in each of formulae (11) to (13):
