Fused polycyclic compound, and preparation method and use thereof

A fused polycyclic compound, having a structure shown below:

• wherein the phenyl ring A is attached to
• 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 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.
