On May 17, 2018, Tsai, Jui-Yi; Xia, Chuanjun; Lin, Chun; Palacios, Adrian U.; Onate, Enrique; Esteruelas, Miguel A.; Boudreault, Pierre-Luc T.; Bajo, Sonia; Olivan, Montserrat published a patent.HPLC of Formula: 1349171-28-3 The title of the patent was Organic electroluminescent iridium complexes having three bidentate ligands. And the patent contained the following:
Methods of method of preparing a metal complex having the formula M(LA)(LB)(LC) are discussed which entail providing a precursor metal complex having the formula (LA)(LB)M-(X)2-M(LA)(LB), in which M is a metal, ligand LA and ligand LB (X = halogen; rings A-D are each independently selected from a 5-6 membered carbocyclic or heterocyclic ring; RA-RD each independently represent mono substitution up to the maximum possible number of substitutions, or no substitution; Z1-Z2 are each independently C or N; RA-RD, RX-RZ are independently selected from H, D, halide, alkyl, etc.; and where any adjacent substituents are optionally joined or fused into a ring); reacting the precursor metal complex with a first reagent to obtain the metal complex having the formula M(LA)(LB)(LC), where LC (RX-RZ are each independently selected from H, D, halide, alkyl, etc.), rings C’ and D’ are each independently selected from a 5-6 membered carbocyclic or heterocyclic ring; C1′ = anionic donor C atom; C2′ = neutral carbene C atom; RC’-RD’ are independently selected from H, D, halide, alkyl, etc., and rings A’ and B’ are each independently selected from a 5-6 membered carbocyclic or heterocyclic ring; Z1′ = anionic donor C atom; Z2′ = neutral N atom; RA’-RB’ are independently selected from H, D, halide, alkyl, etc. The experimental process involved the reaction of 2-(2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pyridine(cas: 1349171-28-3).HPLC of Formula: 1349171-28-3
