By loading from the gas phase C60 can be incorporated into molecular sieves. C60 uptake in the micropore system of the aluminophosphates VPI-5 (picture on the right) and AlPO4-8 was proven by combined thermogravimetry and differential thermal analysis, IR spectroscopy, and sorption measurements. The preliminary NMR results give indications that the free isotropic rotation of C60 in these compounds is restricted.
