Abstract

The invention discloses a derivative of 10-carbonyl-10H-indene[1,2-b][1,2,5] thiadiazole[3,4-g] quinoxaline and application thereof in the technical field of organic electroluminescence. The novel compound is stable in property, and has the high glass transition temperature and molecular thermal stability due to the non-plane heterocyclic ring structure, and a good amorphous film can be easily formed to be applied in the field of organic electroluminescence and used as an electronic transmission material. The general structural formula of the compound is show in the description.

Description

technical field [0001] The invention relates to a novel OLED material and its application, belonging to the field of organic photoelectric materials. 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. It 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 light-emitting device, and the positive and negative charges in the functional materia...
