Abstract
The present disclosure provides a boron heterocyclic compound having a structure represented by a chemical formula 1, wherein Land Lare each independently selected from the group consisting of C6-C30 aryl, C6-C30 fused aryl, C4-C30 heteroaryl, and C4-C30 fused heteroaryl; and Rand Rare each independently selected from the group consisting of carbazolyl, a carbazolyl-derived group, acridinyl, an acridinyl-derived group, diarylamino, and a diarylamino-derived group. The double boron heterocyclic structure functions as an electron acceptor and a linker. In the present disclosure, by attaching a group having a large steric hindrance to the boron atom of the boron heterocyclic ring, the molecules the compound are prevented from aggregating, and thus a π-aggregation or excimer formed by direct accumulation of the conjugate plane is avoided, thereby improving the light-emitting efficiency. The present disclosure further provides a display panel and a display apparatus.
