The term organic zeolite has been introduced by R.M. Barrer, some 35 years ago to define solids able to reversibly absorb hydrophobic (organic) species.  The original meaning of zeolite as ‘boiling stone’ may find its illustration in organic zeolites also when the stone containing volatile compounds as the guest species is exposed to open air. It is thus common characteristic for inorganic or organic zeolites that the solid host structure is preserved when the guest is desorbed. However, such ‘stability’ in organic zeolites usually refers to metastability rather, since the ‘empty’ host lattices are not stable in the thermodynamic understanding.  Host materials which display ability to form organic zeolites are molecular materials (organic and organometallic) but also inorganic like water which can bind in some of its solid phases guest species in a hydrophobic way. There is much experimental evidence on material properties of the compounds which clearly indicate a nonlocal character of interactions which determine their macroscopic properties. These are: Sorption site generation on guest uptake or, put in other words, sorption of some amount of a guest promotes further sorption via generation of new sites, up to a certain saturation stoichiometry; Guest-host interaction, expressed as partial enthalpies of sorption, depend strongly on the amount and type of guest species residing at remote sites; Host lattice transformations display sensitivity to long range interactions. It refers both to the pretransition states  (supersaturated lattices) and order-disorder type of transitions.  All these phenomena point on the importance of intermolecular communication in condensed supramolecular systems which seems to be a challenge for physicochemistry of supramolecular materials.
