General Rule for the Stabilization of Fullerene Cages Encapsulating Trimetallic Nitride Templates

摘要

Fullerenes containing a trimetallic nitride template (TNT) within the cage are a particularly interesting class of endohedral metallofullerenes.Not only are the cage properties modified by the presence of the incarcerated group but,almost uniquely among endohedral metallofullerenes,they are quite stable.Furthermore,they can be produced in multimilligram quantities,and these amounts should increase in the future.The electronic effect of the TNT is such that some fullerenes of sizes and symmetry that are otherwise relatively unstable become available for investigation.
