Abstract
A host material may be used for the separation of elements or compounds, wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material, and wherein said interconnections are closed for a proportion of the time or have a static pore limiting diameter which is smaller than the static dimension of the guest material. Applications include separations of rare gases, chiral molecules, and alkanes. One class of suitable host materials may be made by imine condensation.
Claims27
Use of a host material for the separation of elements or compounds,
- wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material,
- wherein said interconnections are closed for a proportion of the time,
- wherein the host comprises molecular cages prepared by the condensation of aldehydes and amines in a cycloimination reaction;
- and
- wherein said use is effective for the separation of rare gases, or
- wherein said use is effective for enantioselective separation, or
- wherein said use is effective for the separation of alkane isomers or mixtures of different alkanes.
Use of a host material for the separation of rare gases,
- wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material,
- wherein said interconnections have a static pore limiting diameter which is smaller than the static dimension of the guest material,
- wherein the host comprises molecular cages prepared by the condensation of aldehydes and amines in a cycloimination reaction, and
- wherein said use is effective for the separation of rare gases.
Use of a host material for the enantioselective separation of compounds,
- wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be enantiomerically separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material,
- wherein said interconnections have a static pore limiting diameter which is smaller than the static dimension of the guest material,
- wherein the host comprises molecular cages prepared by the condensation of aldehydes and amines in a cycloimination reaction, and
- wherein said use is effective for enantioselective separation;
- or,
- use of a host material for the separation of alkanes,
- wherein the host material is an organic molecular solid with suitable cavities for accommodating a guest material to be separated, and with interconnections between the cavities to allow the guest material to diffuse through the host material,
- wherein said interconnections have a static pore limiting diameter which is smaller than the static dimension of the guest material,
- wherein the host comprises molecular cages prepared by the condensation of aldehydes and amines in a cycloimination reaction, and
- wherein said use is effective for the separation of alkane isomers or mixtures of different alkanes.
