technical field [0001] The invention relates to the technical field of photothermal conversion functional coordination polymer materials, in particular to a three-dimensional copper carboxylate fullerene metal organic framework material and its preparation method and application. Background technique [0002] C 60 It is the third allotrope of carbon reported in 1985. C 60 It is a spherical molecule composed of 60 carbon atoms, with a relative molecular mass of 720, C 60 With 30 carbon-carbon double bonds, each carbon atom provides 1 p orbital electron overlapping each other to form a conjugated system containing 30 pairs of π electrons. Due to its unique spherical molecular structure and its electronic structure, it has been widely studied in the fields of photothermal, photoelectric, electrical, magnetic and other special materials. However, currently C 60 Related materials have not been studied in the field of photothermal functional materials. [0003] At present, t...

AI Technical Summary

Problems solved by technology

but the existing C 60 Complex materials, most of the transition metals used are noble metals such as Pd, Pt, Ru, Os, Rh, Ir, etc., which are expensive and seriously restrict their practical application; in addition, most C 60 The complex is prepared by the traditional low-temperature solution method, that is, it is prepared with a low-boiling point solvent at room temperature or not higher than the boiling point of the solvent and under normal pressure (1 atmosphere)

Most of the complexes prepared by these low-temperature solution methods are oligonuclear molecular complexes, and their photothermal conversion ability and photothermal stability are very limited, so the photothermal conversion efficiency is not high; at the same time, some complexes belong to amorphous nanostructures. Materials whose crystal structure is not clear, which is not conducive to the study of the relationship between their structure and functional properties
