On December 3, 2021, Guo, Jianhua; Li, Mengru; Lu, Ying; Sun, Yue published a patent.Recommanded Product: 160377-42-4 The title of the patent was Preparation of compounds containing benzo five membered heterocycles and organic electroluminescent devices. And the patent contained the following:
The invention discloses a preparation of compounds containing benzo five membered heterocycles and organic electronic devices, which improves the luminous efficiency of the device and prolongs the service life of the device. The compounds containing benzo five membered heterocycles were shown in formula I, Y is selected from any one of O atom, S atom, C (Rx) 2 and N(Ry); the Rx and Ry are the same or different from each other, and are independently selected from hydrogen, deuterium, cyano, nitro, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C3-C12 cycloalkyl, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C3-C30 heteroaryl any one of the rings formed by the condensation of the substituted or unsubstituted aliphatic ring of C3- C30 and the aromatic ring of C6- C30; the two adjacent Rx can be connected to form a substituted or unsubstituted ring, or any of Rx and Ry can be directly bonded with L0; when the Rx and Ry are directly bonded with L0, the Rx and Ry are independently selected from any one of single bond, substituted or unsubstituted C6-C30 arylene, substituted or unsubstituted heteroarylene; the Z is selected from any one of O atom and S atom; the Ar1 is selected from substituted or unsubstituted C3-C12 cycloalkyl, substituted or unsubstituted C3-C12 heterocycloalkyl, etc. The title compound was prepared by a multi-step reaction. The invention discloses an organic electroluminescent device, which comprises the components containing benzo five member heterocycles. The experimental process involved the reaction of 5-(4-Bromophenyl)pyrimidine(cas: 160377-42-4).Recommanded Product: 160377-42-4
