Embodiment Construction

[0027] 1. Preparation of water-soluble poly-γ-cyclodextrin-C 60 Supramolecular clathrate

[0028] 1. Preparation of water-soluble γ-CD polymer

[0029] Add 20 g γ-CD into 40 mL 30wt% NaOH aqueous solution, stir at room temperature until γ-CD dissolves. In a water bath at 30 °C, 15 mL of epichlorohydrin was added to the mixture, stirred for 24 h, and cooled to room temperature. After the salt is removed by dialysis, the solution is evaporated to a viscous state, anhydrous ethanol is added to precipitate a white solid, filtered, and vacuum-dried for 24 h (vacuum degree is 1200-4800 Pa, drying temperature is 50-70 ℃), that is A water-soluble γ-CD polymer was obtained.

[0030] 2. Preparation C 60 and poly-gamma-cyclodextrin mixture

[0031] Weigh 50 mg C 60 Put 300-500 mg of water-soluble γ-CD polymer prepared in the previous step into an agate mortar, grind for 10-15 min, and mix well to obtain C 60 and poly-gamma-cyclodextrin mixture.

Abstract

The invention discloses a water-soluble poly gamma cyclodextrin-C60 supermolecule clathrate compound as well as a preparation method thereof, and relates to the technical field of supramolecular chemistry. The preparation method comprises the following steps of: placing the poly gamma cyclodextrin and fullerene C60 in ultrasonic treatment after mixing and stirring by using water as a solvent, and carrying out rotary evaporation until the mixture is thick; and then, obtaining the water-soluble poly gamma cyclodextrin-C60 supermolecule clathrate compound through vacuum-drying. The prepared clathrate compound contains a complex of 1wt%-50wt% of the poly gamma cyclodextrin, and concentration of the lathrate compound for dispersing the fullerene C60 in water is 10g / L. According to the invention, non-covalent bonds interact, water is used as the solvent, and the poly gamma cyclodextrin is used as a solubilizer, so that negative ion liquor pretreatment does not needed to be carried out onto C60, and the structure of the C60 is not damaged. The method disclosed by the invention is simple and convenient to operate, easily controllable in condition and capable of realizing industrialization.

Description

technical field [0001] The invention relates to the technical field of supramolecular chemistry, in particular to the technical field of production of cyclodextrins with hydrophobic cavities, and also relates to the improvement of fullerene C 60 Water-soluble technical field. Background technique [0002] Supramolecular chemistry is about the chemistry of a whole with high complexity and a certain organization formed by the combination of several chemical species through intermolecular interactions. In this whole, each component also maintains certain inherent physical and chemical properties, and at the same time exhibits certain overall functions due to mutual influence or disturbance. The microscopic unit of the supramolecular system is composed of several or even many molecules or ions of different compounds or other particles with certain chemical properties that can exist alone. The aggregation number can be definite or indeterminate, which is essentially different f...
