Abstract

The invention discloses a fullerene derivative micrometer flower and a preparation method thereof. The micrometer flower is formed by a fullerene C60 derivative, and particularly is formed by the fullerene C60 derivative N-methyl-2-[4-dimethylamino] phenyl-3,4-fulleropyrrolidine which is shaped like a spherical flower, and the spherical flower is formed by mutually crossed and standing micrometer fragments having a fragment length of 3-5[mu]m, a fragment height of 1-3[mu]m, and a fragment thickness of 20-30 [mu]m, and is of a single crystalline state structure. The method comprises the following steps: a carbon tetrachloride solution of the N-methyl-2-[4-dimethylamino] phenyl-3,4-fulleropyrrolidine and an isopropanol solution of hexadecyl trimethyl ammonium bromide are mixed and stirred to obtain a mixed liquor, wherein the volume ratio of the carbon tetrachloride solution of the N-methyl-2-[4-dimethylamino] phenyl-3,4-fulleropyrrolidine and the isopropanol solution of hexadecyl trimethyl ammonium bromide is 1:1-6. The mixed liquor is treated by alternative solid-liquid separating and washing and then the fullerene derivative micrometer flower is obtained. The fullerene derivative micrometer flower can be widely used in the field of cleaning agents, catalyst and hydrophobic materials and the like.

Description

technical field [0001] The invention relates to a derivative micron flower and a preparation method thereof, in particular to a fullerene derivative micron flower and a preparation method thereof. Background technique [0002] Existing studies have shown that N-methyl-2-[4-dimethylamino]phenyl-3,4-fullerenylpyrrolidine, one of the fullerene C60 derivatives, can be widely used in Optical materials, detergents, catalysts, hydrophobic materials and animal anti-cancer substances in the medical field. Recently, various efforts have been made to obtain N-methyl-2-[4-dimethylamino]phenyl-3,4-fullerenylpyrrolidine, such as Photoinduced Intramolecular Electron Transfer in a Bridged C 60 (Acceptor)-Aniline (Donor) System. Photophysical Properties of the First “Active” Fullerene Diad, J.Am.Chem.Soc.1995, 117, 4093-4099 (in C 60 (Electron-withdrawing group)-aniline (electron-donating group) as a bridge system, through photo-induced intramolecular electron transfer, studying the physic...
