  • Preparation of luminescent iridium complexes and precursors thereof
    Patent number: 8618295
    Abstract: Synthetic processes for preparing luminescent iridium complexes and precursors thereof are provided. The method employs water as the reaction solvent to prepare luminescent iridium complexes in two different ways. In the first way, a precursor [Ir2(C11NR8)4I2] (Formula I) is prepared from one of IrCl3, M3IrCl6 (M=Li, Na, K) and [Ir2(C11NR8)4Cl2], and then the precursor [Ir2(C11NR8)4I2] is converted into one of the two luminescent iridium isomeric complexes [Ir(C11NR8)2(C11NR?8)] (Formula II). In the second way, a metal complex IrCl3 or M3IrCl6 (M=Li, Na, K), HC11NR8 and a base are converted selectively into one of the two iridium isomeric complexes [Ir(C11NR8)3] (Formula VIII). Herein, R and R? are defined the same as the specification.

  • Preparation of luminescent iridium complexes and precursors thereof
    Publication number: 20110251391
    Abstract: In the present invention, novel synthetic processes for preparing luminescent iridium complexes and precursors thereof are provided. The method employs water as the reaction solvent to prepare luminescent iridium complexes in two different ways. In the first way, a precursor [Ir2(C11NR8)4I2] (Formula I) is prepared from one of IrCl3, M3IrCl6 (M=Li, Na, K) and [Ir2(C11NR8)4Cl2], and then the precursor [Ir2(C11NR8)4I2] is converted into luminescent iridium complexes [Ir(C11NR8)2(C11NR?8)] (Formula II). In the second way, a metal complex IrCl3 or M3IrCl6 (M=Li, Na, K), HC11NR8 and a base are converted directly into the iridium complexes [Ir(C11NR8)3] (Formula VIII). Herein, R and R? are defined the same as the specification.
