Abstract

The invention discloses a condensed ring type blue light main body material and application thereof and preparation of an application device and relates to the technical field of organic electroluminescence. The condensed ring type blue light main body material comprises a condensed ring compound and other related combinations as main body materials, R1, R2 and X groups in the structural formula of the material have multiple selection results, the main body materials are capable of improving blue light emission efficiency when being applied to the blue light main body material, corresponding devices can be prepared, high blue light purities and good light emission effects can be achieved, and the service life of the obtained device can be also prolonged. By adopting the blue light main body material, the problems that the color purity of blue light of a conventional blue light main body material is low, dark blue light emission and efficient operation are very hard to achieve, and in addition, the service life of a device with the blue light main body material is short, can be solved.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to a condensed ring blue-light host material, its application and the preparation of an application device. Background technique [0002] The organic electroluminescence phenomenon refers to the phenomenon of converting electrical energy into light energy by using organic substances. An organic electroluminescence element utilizing the organic electroluminescence phenomenon generally has a positive electrode, a negative electrode, and a structure including an organic substance layer therebetween. In order to improve the efficiency and lifespan of the organic electroluminescence element, the organic layer has a multilayer structure, and each layer contains different organic substances. Specifically, it may include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like. In thi...
