Abstract

The invention belongs to the technical field of preparation of composite functional materials, and especially relates to a fullerene-calixarene host-guest composite nanocrystal material and a preparation method thereof. A liquid phase treatment process is used to obtain fullerene-calixarene fullerene nanocrystals with a controllable nanocrystal shape, a high crystallinity and a nanometer size. Thehost-guest structure composite nanocrystals are prepared from pure fullerene and p-tert-butylcalix[8]arene through a liquid phase deposition process with an aromatic hydrocarbon as solvent and isopropanol as a precipitant. The method provided by the invention has the advantages of simple process, realization of the effective regulation of the shape in the self-assembling process of the fullerene-calixarene host-guest composite nanocrystals, and improvement of the crystallinity.

Description

technical field [0001] The invention belongs to the technical field of preparation of composite functional materials, in particular to a preparation method of fullerene host-guest composite nanocrystal materials with different compositions and shapes. 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 become a...
