Abstract

The invention discloses a compound containing an aza-5-membered ring and an application thereof in organic electroluminescent devices. The compound is composed of the aza-5-membered ring, has deep HOMO energy level and high hole mobility rate, and is suitable for electronic barrier materials. In addition, the compound has strong group rigidity, has molecules difficult to crystallize and gather, and has good film-forming property. After the compound as an organic electroluminescent functional layer material is applied in OLED devices, the current efficiency, power efficiency and external quantum efficiency of the devices are greatly improved, and the lifetime of the devices is significantly prolonged.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a compound containing an aza five-membered ring and its application in an organic electroluminescent device. 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. 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 light-emitting device, and th...
