| 摘要 |
The present invention relates to a water-soluble fluorescent fullerene derivative and a preparation method thereof, and more particularly to a method of preparing a fullerene derivative having excellent fluorescence in a simple manner by mixing fullerene and a ligand containing a terminal hydroxyl group in a first solvent and reacting the mixture in the presence of a catalyst, and to a water-soluble fluorescent fullerene derivative prepared by the method. According to the method of preparing a water-soluble fluorescent fullerene derivative the present invention, a fullerene derivative having strong fluorescence and hydrophilicity is prepared in a simple and easy manner. In addition, the preparation method enables the intensity and wavelength of fluorescence to be easily controlled depending on the amount of fullerene and the kind of catalyst. The prepared fluorescent fullerene derivative contains a biocompatible ligand, and thus is useful as a biological fluorescent dye. In addition, the fluorescent fullerene derivative has not only fluorescence, but also excellent solubility in a solvent, and thus is useful in the biological field, the medical field, the nanotechnology field, etc. |
