Synthetic example

[0204] In the synthesis examples described below, all temperatures are in degrees Celsius unless otherwise stated. Some reagents were purchased from commercial suppliers such as Aldrich Chemical Company, Arco Chemical Company and Alfa Chemical Company, and were used without further purification unless otherwise stated. The rest of the conventional reagents are from Shantou Xilong Chemical Factory, Guangdong Guanghua Chemical Reagent Factory, Guangzhou Chemical Reagent Factory, Tianjin Haoyuyu Chemical Co., Ltd., Tianjin Fuchen Chemical Reagent Factory, Wuhan Xinhuayuan Technology Development Co., Ltd., Qingdao Tenglong It can be purchased from Chemical Reagent Co., Ltd. and Qingdao Ocean Chemical Factory. Anhydrous tetrahydrofuran, dioxane, toluene, ether and other anhydrous solvents are obtained by reflux drying of metal sodium. Anhydrous dichloromethane and chloroform were obtained by refluxing and drying over calcium hydride. Ethyl acetate, petroleum ether, n-hexane, N,N-...

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescence materials, and in particular relates to a nitrogen-containing compound, an organic electroluminescence device and an electronic device using the same. Background technique [0002] An organic electroluminescence device, such as an organic light emitting diode (OLED), generally includes a cathode and an anode oppositely arranged, and a functional layer arranged between the cathode and the anode. The functional layer is composed of multiple organic or inorganic film layers, and generally includes an organic light-emitting layer, a hole transport layer located between the organic light-emitting layer and the anode, and an electron transport layer located between the organic light-emitting layer and the cathode. When a voltage is applied to the cathode and anode, the two electrodes generate an electric field. Under the action of the electric field, the electrons on the cathode side...
