Abstract

The invention discloses a fullerene derivative micron sheet and a preparation method thereof. The micron sheet is composed of a fullerene C60 derivative, wherein the fullerene C60 derivative is sheet N-methyl-2-[4-dimethylamino]phenyl-3,4-fulleropyrrolidine which has a sheet length in the range from 2 microns to 4 microns, a sheet height in the range from 1 microns to 3 microns and a sheet thickness in the range from 70nm to 80 nm, and is in a single crystalline structure. The method comprises the steps of: mixing the toluene solution of N-methyl-2-[4-dimethylamino]phenyl-3,4-fulleropyrrolidine having the concentration in the range from 0.75 g / L to 2.0 g / L with the isopropanol solution of hexadecyl trimethyl ammonium bromide having the concentration from 3 mmol / L to 7 mmol / L, and then stirring for at least 20 min, thus obtaining mixed solution, wherein the volume ratio of the toluene solution of N-methyl-2-[4-dimethylamino]phenyl-3,4-fulleropyrrolidine to the isopropanol solution of hexadecyl trimethyl ammonium bromide is 1: (1-6); and finally, alternately performing solid-liquid separation and washing treatment on the mixed solution, thereby obtaining the fullerene derivative micron sheet. The fullerene derivative micron sheet can be widely applied to the fields of cleanser, catalyst, hydrophobic material and the like.

Description

technical field [0001] The invention relates to a derivative microsheet and a preparation method thereof, in particular to a fullerene derivative microsheet and a preparation method thereof. Background technique [0002] Existing studies have shown that as fullerene C 60 N-methyl-2-[4-dimethylamino]phenyl-3,4-fullerenylpyrrolidine, one of the derivatives, can be widely used in optical materials, cleaning agents, 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 ph...
