Abstract

Using an open-cage C60 derivative possessing an orifice designed on the basis of computational studies, we have experimentally demonstrated the quantitative encapsulation of H2O as well as effective conversion into H2O@C60 in an overall yield remarkably higher than the previously reported methods by ca. 2-5 times.
