Abstract

The invention relates to a novel organic compound, especially relates to a perimidine derivative, and further discloses an application of the perimidine derivative in the production of an organic electroluminescence device. The perimidine derivative has a good carrier transfer property, and can be used in the OLED as an electron transportation material and a phosphorescence host material. Device test data shows that the derivative is used as the electron transportation material in the OLED, and the derivative has an excellent electron injectivity, a high mobility and a high triplet state energy level, so the derivative can significantly reduce the lighting and working voltages of the device, and can improve the efficiency of the device; and the derivative is used as the phosphorescence host material in the OLED, has balanced hole and electron transporting performances, has an appropriate band gap to facilitate the significant reduction of the lighting and working voltages of the device, and has the high triplet state energy level to facilitate the effective transportation of exciton energy to a phosphorescence dye in order to improve the efficiency of the device.

Description

technical field [0001] The invention relates to a novel organic compound, in particular to a perylene diazepine derivative, and further discloses its application for preparing an organic electroluminescence device. Background technique [0002] The phenomenon of electroluminescence was first discovered in the 1930s. The original luminescent material was ZnS powder, and LED technology was developed from it, which is now widely used in energy-saving light sources. The phenomenon of organic electroluminescence was first discovered by Pope et al. in 1963. They found that the single-layer crystal of anthracene can emit weak blue light under the drive of voltage above 100V. Until 1987, Dr. Deng Qingyun and others from Kodak made organic fluorescent dyes into double-layer devices by vacuum evaporation. When the driving voltage was less than 10V, the external quantum efficiency reached 1%, making organic electroluminescent materials and The device has the possibility of practicabil...
