Abstract

The invention relates to an organic compound containing 9,9'-spirobifluorene as a main body. The general structural formula of the organic compound is shown as the general formula (1) in the description. According to the organic compound, 9,9'-spirobifluorene is taken as a parent nucleus and linked with symmetric or asymmetric rigid groups, crystallinity of molecules is broken, aggregation among the molecules is avoided, and the organic compound has high glass transition temperature; when the organic compound is applied to an OLED (organic light emitting diode) device, high film stability canbe kept, and the service life of the OLED device can be prolonged.

Description

technical field

[0001] The invention relates to the technical field of organic photoelectric materials, in particular to a compound material with 9,9'-spirobifluorene as the core structure and its application in the OLED field. 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 light...
