Abstract

The invention discloses a fullerene C60 material loaded by an imine covalent organic framework, a preparation method of the fullerene C60 material and an application of the fullerene C60 material to a supercapacitor, relates to the field of materials, and in particular, relates to the fullerene C60 material loaded by the imine covalent organic framework and the preparation method of the fullerene C60 material. The imine covalent organic framework material is synthesized by taking three small organic molecules DHTA, TAPB and BATA as construction units and using a solvothermal method. Then, on the basis of a click chemical reaction, cuprous iodide serves as a catalyst, a fullerene derivative BBM-C60 is connected into a covalent organic framework material pore channel through a covalent bond, and preparation of the fullerene C60 ([C60]X-COF) material loaded by the imine covalent organic framework is achieved. The synthesized material retains the unique pi electron conjugation system and good electron transmission characteristic of fullerene C60, and even distribution of fullerene C60 in space is realized through a COF material as a template, so that the problems of insufficient utilization efficiency and low performance of the fullerene material caused by agglomeration are solved; and the application of the fullerene C60 material in the field of supercapacitors is realized.

Description

technical field [0001] The present invention relates to the field of materials, in particular to fullerenes supported by covalent organic frameworks C 60 Materials and their preparation methods. Background technique [0002] Due to its excellent electron transport performance, unique π-electron conjugated system and high electron affinity, fullerene materials have excellent performance in the fields of thermoelectricity, solar cells, and molecular electronics. In addition, in the field of energy storage materials, rich Lenes also have great potential as a special class of carbon materials. However, due to the strong π-π interaction, fullerenes are prone to agglomeration in an aggregated state. When used as an electrode material, its surface is difficult to be fully contacted by the electrolyte, resulting in poor electrochemical performance. In order to solve this problem, it is necessary to use certain porous template materials to limit the occurrence of agglomeration. ...
