Patent number: 10700295Abstract: The present invention provides complexes of the formula (L)M(X), in which M is a metal atom selected from copper, silver and gold; L is a carbene ligand; and X is a monoanionic ligand. The complexes are useful as light emitters in the emissive zone of light-emitting devices such as OLEDs. The present invention also provides organometallic complexes which exhibit RASI photoemission, and the use of the same in light-emitting devices such as OLEDs.Type: GrantFiled: September 9, 2016Date of Patent: June 30, 2020Assignees: UEA ENTERPRISES LIMITED, CAMBRIDGE ENTERPRISE LIMITEDInventors: Manfred Bochmann, Alexander Sergeyevich Romanov, Daniel John Nicholas Credgington, Dawei Di, Le Yang

Patent number: 7851577Abstract: A cationic polymerization process for isoolefins using a zinc halide initiator. The zinc halide initiator is added to a solution of the isoolefin in a suitable solvent, preferably a halocarbon solvent. Polymerization reactions are normally conducted at temperatures high enough to allow the zinc halide initiator to dissolve in the solution. An alkyl halide activator may optionally be used and is preferably added to the solution prior to the zinc halide initiator. A multiolefin may optionally be present in the solution. The process is particularly useful in the formation of isoolefin homopolymers and co-polymers of isoolefins and multiolefins, such as butyl rubber.Type: GrantFiled: February 22, 2007Date of Patent: December 14, 2010Assignee: LANXESS Inc.Inventors: Manfred Bochmann, Antonio Guerrero, Kevin Kulbaba
