Abstract
This invention is directed to the fluorination (or derivatization with alternative chemical species) of fullerene carbon nanocages as an efficient way to (a) facilitate synthesis of endohedral complexes by a significant reduction or elimination of the barriers for the entry of guest-ions, -atoms or molecules, and (b) to preserve the chemical stability of final product.
Claims30
A method comprising the steps of:
- (a) covalently attaching species to the exterior of the fullerene carbon nanocage to form a derivatized fullerene carbon nanocage wherein the derivatized fullerene carbon nanocage is a fluorinated fullerene nanocage;
- (b) inserting an endohedral doping agent into the derivatized fullerene carbon nanocage.
A method comprising:
- (a) derivatizing a fullerene with a fluorine specie;
- and
- (b) endohedrally modifying the fullerene.
A composition comprising:
- (a) a fluorine-derivatized fullerene;
- (b) a first species covalently attached to the fullerene;
- and
- (c) a second species endohedrally located in the fullerene.
