On July 14, 2022, Zhang, Kongyan; Ma, Tiantian; Zhang, Heming published a patent.Quality Control of 7-Bromo-2-phenylbenzo[d]oxazole The title of the patent was Carbazole-triazine compound, and electronic element and electronic device using same. And the patent contained the following:
The application relates to carbazole-triazine compounds I, and electronic elements and electronic devices using same. Compounds of formula I wherein T is -(L3-L4-A2)m; A1 and A2 are independently (un)substituted benzoxazolyl, (un)substituted triazinyl, etc.; m is 1-2; L1-L4 are independently a single bond, (un)substituted C6-30 arylene, C2-30 heteroarylene; R1 and R2 are independently D, halo, C1-10 alkyl, C3-10 cycloalkyl, C1-10 alkoxy, C6-30 aryl, etc.; n1 and n2 are independently 0-4; and their preparation method, as well as the use in OLEDs thereof, are claimed. Example compound II was prepared by using reductive cyclization, Suzuki cross coupling and condensation as the key steps. The organic compounds I provided in the present application can be used in organic electroluminescent devices, and can improve the performance of the organic electroluminescent devices. The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).Quality Control of 7-Bromo-2-phenylbenzo[d]oxazole
