Embodiment 1
[0043] 1. Synthesis of triplet donor materials
[0044]
[0045] Under nitrogen protection, 426 mg (0.35 mmol) of the Ir complex precursor shown in formula A-1, 839 mg (1.45 mmol) of 2,2'-bipyridyl derivatives shown in formula B-1 were added to 60 mL of methanol and di In a mixed solvent with a volume ratio of 1:3 of methyl chloride, heating and stirring, reflux reaction at 60° C. for 24 hours, the disappearance of the reaction raw materials was detected by TLC, and the reaction was terminated. After cooling down to room temperature, the solvent was evaporated under reduced pressure, and the resulting crude product was separated and purified by column chromatography using a mixture of dichloromethane and ethyl acetate with a volume ratio of 3:1 as the mobile phase and silica gel as the stationary phase to obtain formula I The triplet donor material (referred to as Ir-Cl) shown in -1 has a yield of 64%, and its structural characterization data are as follows:

Embodiment 2
[0057] 1. Synthesis of triplet donor materials
[0058] This step is the same as Step 1 of Example 1 to obtain the triplet donor material shown in formula I-1.
[0059] 2. Synthesis of triplet acceptor materials
[0060]
[0061] Add 90 mg (0.15 mmol) of the Pt complex precursor shown in formula C-1 to 50 mL of a mixed solvent with a volume ratio of methanol and dichloromethane of 2:1, and then add 151 mg (0.28 mmol) of the formula E-1 in sequence Alkynoic acid derivatives containing D-glutamic acid, 1mL (7.17mmol) triethylamine and 3.6mg (0.019mmol) cuprous iodide were reacted in a nitrogen-protected environment at 25°C for 24 hours in the dark, and passed TLC Detect the disappearance of the reaction raw materials, and end the reaction. The solvent was distilled off under reduced pressure, and the obtained crude product was washed successively with tetrahydrofuran and acetonitrile, and then purified and separated by co-precipitation with ether and methanol to obtain the ...
