Example Embodiment
[0029] Example 1
[0030] Add 0.20mmol of Ir(tmfppy) 2 EPIP (200mg) and 0.26mmol of [Pt( t Bu 3 terpy)Cl]PF 6 (198.8mg) (molar ratio 2:2.6) dissolved in a mixed solution consisting of 24mL of dichloromethane and 8mL of triethylamine (molar ratio: 674:113), heated under reflux and stirred for 30 minutes in a dark environment , Then add 20mg cuprous iodide, continue to heat and reflux and stir for 5 days in a dark environment, after the reaction is over, cool to room temperature, add 20mL 0.5M (mol / L) ammonium hexafluorophosphate aqueous solution, stir and react for 30 minutes, Extract three times with dichloromethane, 100mL each time, remove the solvent in the rotary evaporator, and then chromatographically separate the iridium-platinum on a silica gel column with dichloromethane and methanol at a volume ratio of 20:1 as eluents. Binuclear complexes.
[0031] The iridium-platinum dinuclear complex was subjected to nuclear magnetic resonance (see the H spectrum figure 1 ), measured:...

[0033] Example 2
[0034] Add 0.20mmol of Ir(tmfppy) 2 EPIP (200mg) and 0.32mmol of [Pt( t Bu 3 terpy)Cl]PF 6 (248.5mg) (molar ratio 2:3.2) was dissolved in a mixed solution consisting of 24mL dichloromethane and 8mL triethylamine (molar ratio: 674:113), heated under reflux and stirred for 28 minutes in a dark environment Then add 18mg cuprous iodide, continue to heat and reflux and stir for 100 hours in a dark environment, after the reaction is over, cool to room temperature, add 10mL 0.5M ammonium hexafluorophosphate aqueous solution, stir and react for 32 minutes, and extract with dichloromethane Three times, 100 mL each time, the solvent was removed in the rotary evaporator, and then chromatographic separation was performed on a silica gel column using dichloromethane and methanol in a volume ratio of 20:1 as eluents to obtain an iridium-platinum dinuclear complex. The H spectrum and mass spectrum of the product are completely consistent with Example 1, so they are not provid...
