Construction of homochiral alkaline–lanthanide heteronuclear helicates with Na+-selective bonding in the self-assembly process†
Abstract
A supramolecular approach to distinguish Na+ from other biologically important metal ions was demonstrated. By designing ligands reasonably, Na+-selective bonding was achieved in the construction of homochiral alkaline–lanthanide heteronuclear helicates, which was further confirmed by mixed-metal self-assembly experiments and 1H-NMR spectra.
