| Abstract | C-60 and its derivatives have become a research hotspot because of their unique structures, physical and chemical properties. The fluorescence properties of C-60 and its derivatives are an important research embranchment of the fullerene science field. In the present paper the fluorescence properties of C-60-glucocorticoids were firstly investigated. When excited with the wavelength of 350 nm at room temperature, C-60-glucocorticoids displayed the fluorescence emission in chloroform at 447 nm. The sixty carbon atoms of C-60 molecule are equivalent, belonging to the Ih group, and presenting high symmetry. It is difficult to observe the fluorescence of C-60 under the same condition because of the high symmetry of C-60 molecule. The fluorescence emission of C-60-glucocorticoids is probably due to the decrease in the high symmetry of C-60 molecule. Moreover, the fluorescence emission at 447 nm of a series of concentrations (10-13 mu mol center dot L-1) of C-60-glucocorticoids chloroform solutions excited at 350 nm was determined, and the result indicated that the C-60-glucocorticoids in chloroform could quench itself's fluorescence intensity. Within the concentration range of 10-64 mu mol center dot L-1, the fluorescence intensity increased along with the accretion of the concentration. When the concentration of C-60-glucocorticoids was greater than 64 mu mol center dot L-1 the fluorescence intensity decreased gradually. |
