Problems solved by technology

At the same time, there is a strong intramolecular charge transfer between the donor and the acceptor of the bipolar host material, which leads to the lowering of the triplet energy level of the material itself, which limits its application in industrial production.

Abstract

The invention discloses a compound taking quinazolinone as a core and applications of the compound on OLED. The compound takes quinazolinone as a core and has the characteristics that molecules are difficult to crystalize and aggregate and the film forming property is good. When the compound is used as a main body material of a luminescent layer of an OLED, the current efficiency, power efficiency and external quantum efficiency of the device can be greatly improved; and in addition, the service life of the device can be obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound of quinazoline derivatives and its application as a light-emitting layer material in an organic light-emitting diode. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. [0003] The OLED light-emitting device is like a sandwich structure, including electrode material film layers, and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both ends of the OLED ...
