Abstract

The invention belongs to the technical field of compound preparation, particularly relates to a fullerene derivative microflower and further discloses a preparation method of the fullerene derivative microflower. The preparation method is based on the known surfactant assisted self-assembly method in the prior art and is further developed. The stirring condition of a N-methyl-2-(4-dimethyl amidogen) phenyl-3,4-fullerene pyrrolidine carbon tetrachloride solution and a hexadecyl trimethyl ammonium bromide isopropanol solution is optimized, and the obtained N-methyl-2-(4-dimethyl amidogen) phenyl-3,4-fullerene pyrrolidine microflower is of a spherical flower-shaped structure, the spherical flower is composed of curved surface microsheets standing in a mutually-crossed mode, and the microsheets are of a single crystalline structure and are 1-2 micrometers long, 1-2 micrometers high and 10-20 manometers thick.

Description

technical field [0001] The invention belongs to the technical field of compound preparation, specifically relates to a fullerene derivative micron flower, and further discloses a preparation method thereof. Background technique [0002] In 1985, when scientists such as R.F.Crul, R.E.Smallay and H.W.Kroto of the United Kingdom used high-energy laser pulses to graphite, they accidentally discovered a series of carbon ion clusters represented by C60, which were later called fullerenes or football enes. Fullerene thus stands out as the third allotrope of carbon. Later, inspired by the vaulted dome designed by architectural designer Buckminster Fuller, Kroto and others finally determined that C60 has a closed spherical cage structure similar to the vaulted dome, which is consistent with the "stable" nature of C60 match. [0003] In the research on fullerenes, the application of fullerenes has always been one of the main topics that scientists are most concerned about. Fulleren...
