Patent number: 11958870Abstract: An asymmetric tetradentate metal complex of a N{circumflex over (?)}C{circumflex over (?)}C{circumflex over (?)}N comprising tetradentate ligand has a metal connected to binding sites which are connected to each other via three or four covalent bonds that can be either single or double bonds with bridging linkers reside between C{circumflex over (?)}C and C{circumflex over (?)}N moieties. These linkers result in three-dimension metal complexes with distorted square planar geometries. The four donor atoms coordinate to a metal center. Upon metal binding a 5-6-6 membered metallocycle is formed upon chelation including a first nitrogen donor bond, a first metal-carbon bond, a second metal-carbon bond, and a second nitrogen donor bond. The light emission from these metal complexes can be tuned by the ligand structure over the entire visible spectrum.Type: GrantFiled: January 18, 2019Date of Patent: April 16, 2024Assignee: The University of Hong KongInventors: Chi Ming Che, Wai Hung Ang, Mao Mao, Gang Cheng
