Abstract

The invention discloses an organic compound containing dimethylanthracene and application thereof in an organic light-emitting device (OLED). A structure general formula of the organic compound is represented as the formula (I). The compound has high glass transition temperature and molecular thermostability, appropriate HOMO and LUMO energy level and high Eg. Through structural optimization of the device, photoelectric performance and service life of the OLED can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a compound material containing a dimethyl anthracene structure as a central skeleton and its application in the field of OLEDs. 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 e...
