Abstract
Using nitrene chemistry, catechol functionalized aziridinofullerenes (CAC(60)) were synthesized by reacting N-(3-azidopropyl)-2-(3,4-dihydroxyphenyl)acetamide with C-60. Synthesis of CAC(60) was confirmed by Fourier-transform infrared, Raman and X-ray photoelectron spectroscopies, and Thermogravimetric analysis. The photocatalytic activity of CAC(60) was evaluated by measuring photodegradation of a pharmaceutical compound, cimetidine. CAC(60) exhibited the instantaneous adsorption of cimetidine, followed by effective photooxidation under visible as well as ultraviolet irradiations. From the comparison of photodegradation behaviors of unmodified control C-60, amine functionalized aziridinofullerenes, and CAC(60), we concluded that the aziridine and catechol moieties were responsible for the visible light activity and hydrophilicity of CAC(60), respectively.
