Abstract

The invention provides a method for preparing endohedral fullerene crystal. The method comprises the following steps of: dissolving endohedral fullerene which is represented by Sc3N@C80 into a benign solvent, and adding a poor solvent in the benign solvent; carrying out ultrasonic treatment for obtained mixture, then standing, and carrying out centrifugal purification for three times, wherein the volume ratio between the benign solvent and the poor solvent is 1 : (2-5). According to the method disclosed by the invention, by adopting the benign solvent and the poor solvent of the endohedral fullerene in a certain volume ratio, the endohedral fullerene single crystal with uniform size can be obtained after the ultrasonic treatment, and the method has the advantages that the step is simple, the growth period is short, the raw material source is wide, the price is cheap, the production cost is low, large-scale production can be carried out, and the economic benefit is excellent.

Description

technical field

[0001] The invention relates to the field of fullerenes, in particular to a method for preparing embedded fullerene crystals. Background technique

[0002] Embedded fullerene is a kind of new type of fullerene with special structure and properties, generally with MC 2n Indicates that M represents a metal element. Embedded fullerenes have broad application prospects in the fields of energy, biomedicine, lasers, superconductivity, catalysis, organic ferromagnets, nonlinear optical materials, field-effect diodes, and information science. Among them, the fullerene with embedded nitride atomic clusters discovered in 1999 (using Sc 3 NC 80 ) is considered to be a major breakthrough in the field of embedded fullerenes and has become a research hotspot in the field of fullerenes.

[0003] Since micro-nano crystal materials can often improve or change the inherent characteristics of substances, and can be directly applied because of their ordered microstructure, t...
