-
Paragraph 0067-0068, (2019/12/12)
The invention discloses a ketone containing compound and application thereof in organic light-emitting devices, and belongs to the field of semiconductor application. The compound contains a ketone structure and has very high rigidity, and after the structure of a spiroazacyclic anthracene fluorene derivative is connected, the ketone containing compound has the characteristics of being not prone to crystallizing, not prone to gathering and good film-forming property. The ketone containing compound is bipolar, a branched chain is an electron-donating group, due to the fact that the electron-donating ability of groups is different in strong and weak, therefore, the HOMO energy level of the ketone containing compound is different, and the ketone containing compound can be used as different functional layer materials; in addition, the ketone containing compound has a high triplet state energy level, the energy loss can be effectively prevented, and energy transfer is facilitated; therefore, after the ketone containing compound used as organic electroluminescent functional layer materials is applied to OLED devices, the current efficiency, the power efficiency and the external quantum efficiency of the devices are all greatly improved; and meanwhile, prolongation of the service life of the devices is very obvious.
Oxidation and reductive bromination of Bis(4-tert-butylphenyl)aminoxyl
Golubev,Sen'
, p. 1143 - 1149 (2013/10/01)
One-electron oxidation of bis(4-tert-butylphenyl)aminoxyl with antimony pentachloride and bromine leads to the formation of oxoammonium salts with anions SbCl 6 - and Br 3 - respectively. The salt with the Br 3 - anion converted at heating into a mixture of bromodiphenylamines which formed also from the aminoxyl as a result of previously unknown reaction of three-electron reductive bromination. The mechanisms of these reactions were assumed.
