The formation of the inclusion compounds greatly modifies the physical and chemical properties of the guest molecule, mostly in terms of water solubility.
12.
The larger pore size ( 2-50 nm ) of mesoporous materials gives them wider application larger molecules can be admitted, and guest molecules can migrate faster.
13.
Building on this option, Vladimir Broude developed a method of studying the energy spectrum of excitons in the host crystal by changing the isotopic content of guest molecules.
14.
A supramolecular host could bind to a guest molecule in such a way that the guest s labile group is positioned close to the reactive group of the host.
15.
Chemists use the study of intramolecular and intermolecular cooperativity in supramolecular assemblies and macrocyclic compounds such as crown ethers and cryptands, which can act as hosts to guest molecules.
16.
Experimentally, one can determine the concentration of the host guest complex, [ HG ], as a function of the initial concentration of the guest molecules, [ G ] _ o.
17.
According to IUPAC, clathrates are " Inclusion compounds in which the guest molecule is in a cage formed by the host molecule or by a lattice of host molecules ."
18.
The thermodynamic benefits of host guest chemistry are derived from the idea that there is a lower overall Gibbs free energy due to the interaction between host and guest molecules.
19.
With this final substitution, one can solve for the concentration of the host guest complex [ HG ] as a function of the initial concentrations of the host and guest molecules:
20.
For example, raising the temperature in a polymer guest-host system close to its glass-rubber transition temperature before poling increases the mobility of the guest molecules and allows rotation to occur during poling.
