The disclosed synthesis method for Ir complex comprises: loading inert solvent with half volume of the three-necked flask, adding 1mmol IrCl3, and heating to full dissolution; dripping carefully 6-10mmol hexafluoroacetylacetone into the mixed liquid to react for 40-60h at 50-70Deg; filtering the white solid deposit to evaporate and dry; dissolving the obtained solid into 30ml inert solvent at 20Deg; filtering, putting the filtrate into icebox of 5Deg for 24h; finally, filtering, and vacuum drying. This invention solves the low-volatility problem of acetylacetone complex in prior art. |
