CAVITAND

Cavitand

Molecule able to contain another molecule within itself

In chemistry, a cavitand is a container-shaped molecule. The cavity of the cavitand allows it to engage in host–guest chemistry with guest molecules of

Coordination cage

cavitand cages and metalloprisms are some of the more common. Cavitand cages are formed by linking bowl-shaped organic molecules called cavitands. The

Calixarene

Basket-shaped ring molecule able to store other molecules within itself

can hold smaller molecules or ions, calixarenes belong to the class of cavitands known in host–guest chemistry. Calixarene nomenclature is straightforward

Calixarene

Host–guest chemistry

Supramolecular structures held together other than by covalent bonds

rearranged products (isomers of A-CO-B). Organic hosts are occasionally called cavitands. The original definition proposed by Cram includes many classes of molecules:

Resorcinarene

Ring molecule able to hold other molecules within itself

A number of molecular structures are based on this macrocycle, namely cavitands and carcerands. The resorcinarenes are typically prepared by condensation
