On June 25, 2021, Ma, Tiantian; Zhang, Kongyan; Li, Xinxuan; Zheng, Yiyi published a patent.Synthetic Route of 1268137-13-8 The title of the patent was Nitrogen-containing compound, electronic component and electronic device containing the same. And the patent contained the following:
The present invention relates to a nitrogen-containing compound that is represented by the formula I, wherein A and B are independently C6-C30 (un)substituted aryl, aryl, etc.; U1, U2 and U3 are independently selected from N or C(R), and at least one of U1, U2 and U3 is N; each of R, R1, R2, R3, R4, and R5 is independently selected from hydrogen, deuterium, halogen group, cyano group, etc.; n1, n2, n3, n4, n5 are selected from 1, 2, 3 or 4, when n1-n5 is greater than 1; X is selected from S or O; L, L1, L2, L3 and L4 are independently selected from single bonds, (un)substituted arylene groups having 6-30 carbon atoms, and (un)substituted heteroarylene group having 3-30 carbon atoms; and Ar1 and Ar2 are independently selected from (un)substituted aryl groups having 6-30 carbon atoms, and (un)substituted heteroaryl groups having 3-30 carbon atoms. The nitrogen-containing compound can be used in the light-emitting layer material of an organic electroluminescent device, improving the electron transport performance of the device, and improving the luminous efficiency and service life of the device. The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).Synthetic Route of 1268137-13-8
