http://www.thechristhospitalmychart.com/ WebCrown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Modification of the crown-ether by the introduction of four carboxylic groups makes it possible to use this class of compounds as chiral selectors in CE. 132.

WebDec 24, 2024 · Chiral MOFs, which have numerous nanosized chiral helical channels, are appropriate chiral hosts to confine achiral chromophores. In this case, the size matches between the chiral cavities and achiral guests, interactions between the host and guest, and energy levels between the host MOFs and guest should be taken into consideration. WebDec 8, 2024 · The chiral hosts are often liquid crystals, cellulose NCs, supramolecular assemblies or gels, and so forth. Based on such a feasible approach, various CPL-active inorganic nanomaterials were reported. In practice, there are many advanced investigations related to CPL-active inorganic nanomaterials obtained by the chiral assembly. WebJan 11, 2024 · Two kinds of chiral hosts, named (R/S)-BN-mCP and (R/S)-BN-2mCP, are prepared.
