A cavitand is a container shaped molecule.[1] The cavity of the cavitand allows it to engage in host-guest chemistry In supramolecular chemistry, host-guest chemistry describes complexes that are composed of two or more molecules or ions held together in unique structural relationships by hydrogen bonding or by ion pairing or by Van der Waals force other than those of full covalent bonds with guest molecules of a complementary shape and size. Examples include cyclodextrins, calixarenes A calixarene is a macrocycle or cyclic oligomer based on a hydroxyalkylation product of a phenol and an aldehyde . The word calixarene is derived from calix or chalice because this type of molecule resembles a vase and from the word arene that refers to the aromatic building block. Calixarenes have hydrophobic cavities that can hold smaller, and cucurbiturils.
