The crown ether
pores were designed to trap potassium ions, which have a positive charge.
When compared to crown ethers
and cryptants, calixarenes carry metal cations from one phase to the other more selectively.
Introduction The cation selectivity of macrocyclic ligands such as crown ether
and cryptands makes them excellent candidates for analytical applications.
Polythia macrocycles  are the thioether analogs of the crown ethers
(Table 3, Compound 16).
Wang et al., "Structural adjustment during intercalation of macrocyclic crown ether
into LDH via swelling/restoration reaction: staging formation and mechanism insights," Dalton Transactions, vol.
Moreover, trans-dinitro-dibenzo-18-6 crown ether
as selective iron (III) ion ionophore was used for the functionalization of seedless grown ZnO nanorods in 3D on nickel foam substrate.
Synergistic solvent extraction of trivalent lanthanoids with mixtures of 1-phenyl-3-methyl-4-pivaloyl-5-pyrazolone and crown ethers
. Solvent Extr.
This research introduces the use of crown ethers
to shield the growing chains from such unwanted interactions.
He also holds a patient on hydroxamic acid crown ethers
and cryptands have high binding capacities for inorganic cations, such as [Na.sup.+], [K.sup.+], etc.
