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 [Ir

在本发明中,提供了用于制备发光铱配合物及其前体的新型合成方法。该方法采用水作为反应溶剂,以两种不同的方式制备发光铱配合物。在第一种方式中,从IrCl3、M3IrCl6(M=Li, Na, K)和[Ir2(C11NR8)4Cl2]中的一种制备前体[Ir2(C11NR8)4I2](化学式I),然后将前体[Ir2(C11NR8)4I2]转化为发光铱配合物[Ir(C11NR8)2(C11NR′8)](化学式II)。在第二种方式中,金属配合物IrCl3或M3IrCl6(M=Li, Na, K)、HC11NR8和一种碱直接转化为铱配合物[Ir(C11NR8)3](化学式VIII)。这里,R和R'的定义与规范相同。
