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):
该化合物由公式(11)到(13)中的一个表示。R1到R4各自独立地表示由公式(1-1)或类似公式表示的基团,或由公式(2-1),公式(2-2)或类似公式表示的基团。其中至少一个R1到R4是由公式(1-1)或类似公式表示的基团。至少一个R1到R4是由公式(2-1),(2-2)或类似公式表示的基团。例如,X1表示氧原子,硫原子或CR151R152,R101到R110和R151和R152各自独立地表示氢原子或取代基。例如,R161到R168和R171和R180各自独立地表示氢原子或取代基。*各自独立地表示公式(11)到(13)中苯环中碳原子的键合位置。
