Cage Like Materials: Application

Clathrates belong to the zeolite family. As mentioned in the

previous chapters, there is a entanglement between empty or

stuffed fullerenes, buckyballs and the clathrate lattices. The clathrate

host structures are based on strong covalent bonds in all three

directions of the space. They can therefore be described as the

result of the covalent packing of cage-like building blocks. Upon

endohedral doping, they become unusual materials presenting

striking properties related to the more and less important coupling

between the host and guest interpenetrated lattices. Contrary to

common networks, the possibility to encage atoms or molecules

opens a newfield. In this way, by their apparent simplicity, clathrates

are the prototype of the elementary zeolite.
