DIBENZOHETEROCYCLIC COMPOUND AND PREPARATION METHOD AND APPLICATION THEREOF

A dibenzoheterocyclic compound wherein band gaps of HOMO and LUMO energy levels of the dibenzoheterocyclic compound are wide, light can be emitted in a deep blue light-emitting region; and the LUMO energy level of the dibenzoheterocyclic compound is low, so the LUMO energy level matches with an electron transport layer for electrons injection and transport. The dibenzoheterocyclic compound has hole transport performance, so as a light-emitting layer material, the dibenzoheterocyclic compound balances the ratio of electrons to holes in a light-emitting layer increasing the combination probability and improving the device light-emitting efficiency. The spatial configuration of the dibenzoheterocyclic compound avoids material stacking molecules, reduces annihilation of excitons, and inhibits efficiency roll-off. The dibenzoheterocyclic compound has thermal stability, so deep blue light can be emitted efficiently and stably. With an organic light-emitting diode and a deep blue light-emitting device with high light-emitting efficiency, low working voltage can be obtained.
