A compound is represented by one of formulae (11) to (13). In the 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, in the formula (1-1), 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, in the formulae (2-1) to (2-2), 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 the formulae (11) to (13).
化合物由式(11)至(13)之一表示。在式 (11) 至 (13) 中,R1 至 R4 各自独立地代表式 (1-1) 或类似式所代表的基团,或代表式 (2-1)、式 (2-2) 或类似式所代表的基团。R1 至 R4 中至少有一个是式 (1-1) 或类似式所代表的基团。R1 至 R4 中至少有一个是式 (2-1)、(2-2) 或类似式所代表的基团。例如,在式 (1-1) 中,X1 代表
