Embodiment 1

[0046] The synthesis of embodiment 1 compound 1:

[0047] synthetic route:

[0048]

[0049] In a 250ml four-neck flask, under nitrogen atmosphere, add 7.9g of p-3-bromopyridine (0.05mol), 1.44g of Mg powder (0.06mol), 60ml of tetrahydrofuran, heat and reflux for 4 hours, the reaction is complete, and Grignard reagent is generated;

[0050] Dissolve 9.8g xanthanone (0.05mol) in 50ml tetrahydrofuran, add the above-mentioned Grignard reagent dropwise, react at 60°C for 24 hours, a large amount of white precipitate is formed, and finally add saturated NHCl 4 Grignard salt was converted into alcohol; after the reaction was completed, extracted with ether, dried and rotary evaporated, and purified on a silica gel column with a mixed solvent of petroleum ether:dichloromethane (3:2) to obtain slightly yellow compound C (yield 81%); Using DEI-MS to identify the compound, formula C 18 h 13 NO 2 , detection value [M+1] + = 275.72, calculated value 275.09;

[0051] Dissolve 11.0...

Abstract

The invention discloses an organic compound containing a xanthene structure and an application of the organic compound. The structural general formula of the compound is shown in the general formula (1). The compound is high in glass transition temperature and molecular stability, proper in HOMO and LUMO energy level, and relatively high in Eg. Through device structure optimization, the photoelectric property of an OLED device is improved and the service life of the OLED device is prolonged.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a compound material with a xanthene structure as a central skeleton and its application in the field of OLEDs. Background technique [0002] Organic electroluminescence (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 ...
