Embodiment 1

[0040] The skeleton structure bimetallic center organoplatinum metal complex Pt1 of the present embodiment has a chemical formula of C 54 h 39 N 5 Pt 2 , the molecular structure formula is:

[0041]

[0042] Refer to attached figure 1 , the synthesis steps are as follows:

[0043] 0.6mmol precursor With 0.3mmol organic "bridge" structure Put it into a reaction vessel, and add 0.03mmol of catalyst CuI, 30mmol of triethylamine and 15mL of methanol into the reaction vessel under a nitrogen atmosphere. The reaction mixture was heated to 65°C under nitrogen atmosphere and stirred for 12 hours, then cooled to room temperature, resulting in precipitation. The precipitate obtained by filtration was washed three times with deionized water, methanol, and ether, respectively. Then dry it in a vacuum oven and remove the solvent to obtain the bimetallic-centered organic platinum complex Pt1 with a new skeleton structure, with a yield of 73.6%. Its NMR spectrum is as figure 2 ...

Abstract

A bimetallic-centered organoplatinum complex energy conversion material with a skeleton structure, which uses bidentate and monodentate complexes to mix and match, so that both the bidentate ligand and the monodentate ligand can significantly affect the properties of the organoplatinum metal complex. The main ligand, thus increasing the entry points for property regulation to seven at most, which can greatly increase the space for structural design of organoplatinum metal complexes, that is, the properties of organoplatinum metal complexes can be controlled more finely, and more It is easy to meet the special requirements for materials in new application scenarios; the complex structure of the present invention is novel, the number of controllable sites has increased by nearly 3 times, it has good solubility in common organic solvents, has good solution processing performance, and can emit strong The room temperature phosphorescence has very important application value in the preparation of flexible, rollable and wearable energy conversion devices.
