Powder X-ray diffractograms (a) of the composite material where Mn12Ac is adsorbed on the surface of closed (untreated) GMWNT before (orange) and after (blue) washing with acetonitrile, confirming the efficient removal of Mn12Ac molecules from the nanotube surface. The peak labelled with an asterisk is assigned to the nanotube. (b) TGA of Mn12Ac@GMWNT (1) (red) and closed GMWNT after washing (blue).
