Paragraph 0148-0154, (2019/11/20)
The invention relates to the technical field of display, in particular to a cyclic compound and application thereof and an electronic device. The provided cyclic compound at least comprises compoundsshown in formulas 001-011, the cyclic compound has good thermal stability and matching LUMO energy level with adjacent layers, and is used as a p-doped material in a hole transport layer to be appliedto an OLED device, the hole generation can be promoted, thus electrons and holes in the OLED device are more effectively recombined to form excitons, and the obtained OLED device has lower driving voltage, higher carrier binding rate and luminous efficiency.
