1. A fused polycyclic compound, having a structure shown below:

OG Complex Work Unit Chemistry
wherein the phenyl ring A is attached to

OG Complex Work Unit Chemistry
at positions 1 and 2, positions 2 and 3, or positions 3 and 4 to form a fused ring sharing the same side, in which “*” and custom character denotes the points of attachment;
T1 is independently selected from NR24, S, O, BR24, PR24, and C(R24)2, in which R24 is the same or different, and is each independently selected from methyl, deuterated methyl, phenyl, deuterated phenyl, biphenylyl, deuterated biphenylyl, naphthalenyl, and deuterated naphthalenyl;
at least one of T2 and T3 is a single bond, when T2 is a single bond, T3 is S or O, and when T3 is a single bond, T2 is S or O; and
R15-R23 are the same or different, and are each independently selected from hydrogen, deuterium, methyl, deuterated methyl, phenyl, deuterated phenyl, and deuterated methyl substituted phenyl; wherein at least one of R15-R23 is selected from deuterium, deuterated methyl, deuterated phenyl, and deuterated methyl substituted phenyl.
