Abstract

The invention belongs to the technical field of preparation of composite functional materials, and in particular relates to a fullerene C60-calixarene host-guest composite nanocrystal material and a preparation method thereof. According to the invention, pure fullerene C60 raw powder and p-tert-butylcalix[8]arene are adopted as raw materials, aromatic hydrocarbon is adopted as a solvent, isopropanol is adopted as a precipitant, and a host-guest structure composite nanocrystal is prepared by a liquid-phase deposition method. The method provided by the invention has simple process, and can realize the effective regulation of the shape and increase the crystallinity of fullerene-calixarene host-guest composite nanocrystal during a self-assembly process.

Description

technical field [0001] The invention belongs to the technical field of preparation of composite functional materials, in particular to fullerene C with different compositions and shapes 60 Preparation method of host-guest complex nanocrystalline material. Background technique [0002] Fullerenes are a class of pure carbon cage structure materials first discovered by scientists such as Kroto (Nature, Vol. Production. In the fullerene family C 60 and C 70 They are the two most readily available and most abundant members. As semiconductor materials, they have excellent properties such as photophysics, light conduction, superconductivity, and superhardness. Materials composed of fullerene molecules, especially nanomaterials with different dimensions, have great potential application value in the field of functional materials and nanodevices. Therefore, the synthesis of fullerene-based nanocrystalline materials and the optimization of their structures and properties have bec...
