The metal complex shows advantageous intense and long-lived phosphorescence accompanied by exceptional cellular localization properties. The metal complex is highly photostable and highly selective towards hydrogen peroxide, thus, especially suitable for detecting mitochondrial H2O2.Type: GrantFiled: October 27, 2015Date of Patent: February 13, 2018Assignee: City University of Hong KongInventors: Kam Wing Kenneth Lo, Hua Wei Liu, Cho Cheung Lee

Patent number: 9793499Abstract: The present invention provides an organic metal complex having high heat resistance while making it possible to realize electroluminescence with high quantum efficiency as a light-emitting material for organic electroluminescent (EL) element. The present invention relates to an organic iridium complex for an organic EL element, wherein a C—N ligand including a substituent of a tricyclic-based structure obtained by condensing a heterocyclic ring and two benzene rings, and a ?-diketone ligand composed of a propane-1,3-dione having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The complex of the present invention has high heat resistance and contributes to lifetime prolongation of the organic EL element.Type: GrantFiled: June 9, 2015Date of Patent: October 17, 2017Assignees: TANAKA KIKINZOKU KOGYO K.K., OSAKA PREFECTURE UNIVERSITY PUBLIC CORPORATIONInventors: Yasushi Masahiro, Shigeyuki Yagi, Junichi Taniuchi
