Abstract
Very high loadings of C60 and C60- anions in MCM-41 mesoporous materials have been achieved by modifying the channel surface with amino-functional group. Detailed physical properties of these mesoporous materials containing C60 were characterized by EPR, NMR, XRD, FTIR and UV-vis spectroscopic techniques. The surface area and pore size of mesoporous materials were further determined by N2 adsorption-desorption isotherms. The mesopores of MCM-41 show sieving behavior in excluding the larger sized C120O while absorbing the smaller C60 as indicated in the EPR studies. © 2002 Elsevier Science Inc. All rights reserved.
