cryptands การใช้

Shortly after crown compounds, cryptands, were reported by Lehn and co-workers.
Lithium ions may be chemically removed by binding to species such as cryptands or crown ethers.
Such salts can be isolated by the addition of macrocyclic ligands such as crown ether and cryptands.
However, with the help of cryptands and methylamine, pure may be obtained as red crystals isostructural to [ [ sodium nitrite | ] ].
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.
