Title:
METHODS OF MAKING BIS-TRIDENTATE CARBENE COMPLEXES OF RUTHENIUM AND OSMIUM
Document Type and Number:
WIPO Patent Application WO/2012/116234
Kind Code:
A3
Abstract:
Methods of making bis-tridentate carbene complexes of ruthenium and osmium are provided. The use of DMSO solvates of ruthenium(II) and osmium(II) halide salts provides good yields of the corresponding complexes. These materials may be used in OLEDs to provide devices having improved performance
