Abstract

The invention discloses a dimethylanthracene-containing organic compound and an application thereof in organic electroluminescent devices. The organic compound has a general structure represented by a general formula (1) shown in the description. The compound disclosed by the invention has relatively high vitrification temperature and molecular thermal stability, appropriate HOMO and LUMO energy levels and relatively high Eg; and through structural optimization on devices, photoelectric properties of OLED devices can be effectively improved, and service lives of the OLED devices can be effectively prolonged.

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...
