Embodiment 1
[0033] Synthesis of complex Ir1:
[0034] The auxiliary ligand 9,9-bis(9-ethylcarbazol-3-yl)-4,5-diazafluorene (ECAF) (0.42 g) containing 0.76 mmol of bicarrier groups was mixed with 0.33 mmol[Ir(ppy) 2 Cl] 2 (0.35 g) of the mixture was dissolved in 30 ml of ethylene glycol monoethyl ether, and reacted at 130° C. for 10 hours under the protection of nitrogen. Then cool to room temperature, add 20mL of deionized aqueous solution that is dissolved with 0.87g ammonium hexafluorophosphate to the above-mentioned solution under stirring, produce a large amount of precipitation, suction filtration, the precipitation is passed through the column chromatography column (eluent is dichloromethane / Acetone=10:1) was purified to obtain the corresponding complex [Ir(ppy) 2 (ECAF)] PF 6 (Ir1).
Embodiment 2
[0036] Synthesis of complex Ir2:
[0037] The auxiliary ligand 9,9-bis(9-ethylhexylcarbazol-3-yl)-4,5-diazafluorene (EHCAF) (0.49g) containing 0.76mmol of bicarrier groups was mixed with 0.33mmol [Ir(ppy) 2 Cl] 2 (0.35g) of the mixture was dissolved in 30ml of ethylene glycol monoethyl ether, and reacted at 150°C for 12 hours under the protection of nitrogen. Then cool to room temperature, add 20mL of deionized aqueous solution that is dissolved with 0.87g ammonium hexafluorophosphate to the above-mentioned solution under stirring, produce a large amount of precipitation, suction filtration, the precipitation is passed through the column chromatography column (eluent is dichloromethane / Acetone=10:1) was purified to obtain the corresponding complex [Ir(ppy) 2 (EHCAF)]PF 6 (Ir2).
Embodiment 3
[0039] Synthesis of complex Ir3:
[0040] The auxiliary ligand 9,9-bis(9-phenylcarbazol-3-yl)-4,5-diazafluorene (PCAF) (0.49 g) containing 0.76 mmol of bicarrier groups was mixed with 0.33 mmol[Ir(ppy) 2 Cl] 2 (0.35 g) of the mixture was dissolved in 30 ml of ethylene glycol monoethyl ether, and reacted at 160° C. for 15 hours under the protection of nitrogen. Then cool to room temperature, add 20mL of deionized aqueous solution that is dissolved with 0.87g ammonium hexafluorophosphate to the above-mentioned solution under stirring, produce a large amount of precipitation, suction filtration, the precipitation is passed through the column chromatography column (eluent is dichloromethane / Acetone=10:1) was purified to obtain the corresponding complex [Ir(ppy) 2 (PCAF)]PF 6 (Ir3).
[0041] In the above-mentioned embodiment, the deionized aqueous solution of ammonium hexafluorophosphate can be replaced by an aqueous solution of ammonium tetrafluoroborate, and the chemical fo...
