On July 12, 2022, Zhang, Kongyan; Ma, Tiantian; Zhang, Heming published a patent.Formula: C13H8BrNO The title of the patent was Carbazole-triazine compound, and electronic element and electronic device using same. And the patent contained the following:
The present application relates to an organic compound and electronic component and electronic device using the same. The organic compound has a structure represented by the following formula 1, wherein A1 and A2 are independently selected from a structure represented by formula 2 or formula 3; m is 1 or 2. The organic compounds provided herein can be used in an organic electroluminescent device to improve the performance of the organic electroluminescent device. 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).Formula: C13H8BrNO
