Abstract:
1. A method of preparing a nanoparticle, which comprises (a) dissolving a cucurbituril derivative of Formula 1 below in an organic solvent to obtain a reaction solution; (b) adding water to the reaction solution followed by dispersing; (c) distilling the dispersed solution in a temperature range from a boiling point of the organic solvent to 100° C. to remove the organic solvent; and (d) cooling the resultant solution to room temperature: wherein X is O, S, or NH; A R n is an integer of 4 to 20: wherein the nanoparticle is formed by aggregation of the cucurbituril derivatives of Formula 1; and wherein the nanoparticle has a particle size of 10 to 1,000 nm and has a cavity newly formed by the aggregation.
