Abstract

Using nitrene chemistry, catechol functionalized aziridinofullerenes (CAC₆₀) were synthesized by reacting N-(3-azidopropyl)-2-(3,4- dihydroxyphenyl)acetamide with C₆₀. Synthesis of CAC₆₀ was confirmed by Fourier-transform infrared, Raman and X-ray photoelectron spectroscopies, and Thermogravimetric analysis. The photocatalytic activity of CAC₆₀ was evaluated by measuring photodegradation of a pharmaceutical compound, cimetidine. CAC₆₀ 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 C₆₀, amine functionalized aziridinofullerenes, and CAC₆₀, we concluded that the aziridine and catechol moieties were responsible for the visible light activity and hydrophilicity of CAC ₆₀, respectively.
