Abstract

The organic electroluminescent material of the present invention is a new aromatic amine derivative, which is composed of the amine compound through the ether bond linking Ar1 and Ar2 to increase the electron density and improve the related performance, and to adjust the R1~R4 of the amine compound The molecular weight of the ligand and the type of the ligand improve the performance and improve the function. The organic device using amine derivatives in the present invention has high brightness, excellent heat resistance, long life and high efficiency, and its synthesis and purification are relatively simple and low in cost, which can meet the needs of industrialization development.

Description

technical field [0001] The present invention relates to organic electroluminescent compounds and organic electroluminescent devices comprising the same. Specifically, it concerns novel aromatic aromatic compounds as electroluminescent materials and using them as an organic electroluminescent device. Background technique [0002] An organic electroluminescent device generally consists of two opposite electrodes and at least one layer of organic light-emitting compound interposed between the two electrodes. Charges are injected into the organic layer formed between the anode and cathode to form electron and hole pairs, which cause light emission from organic compounds having fluorescent or phosphorescent properties. [0003] Organic electroluminescent device (OLED) is a new type of flat display device, which has the characteristics of energy saving, fast response, stable color, strong environmental adaptability, no radiation, long life, light weight and thin thickness.
