The present disclosure relates to the field of OLED technologies and provides a compound having TADF property. In an embodiment, the compound has a structure represented by Formula (1), in which Land Lare each a hydrogen atom, phenyl, naphthyl, anthracyl, pyridyl, pyrimidinyl, and pyrazinyl; Rand Rare each aryl or and heteroaryl, such as a carbazole-derived group, an acridine-derived group, diarylamino, a diarylamine-derived group, and the like. In the present disclosure, the double boron heterocyclic structure functions not only as an electron acceptor but also as a linker. In the compound according to 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 &#x3c0;-aggregation or excimer formed by direct accumulation of the conjugate plane is avoided, thereby improving the light-emitting efficiency.
