The ligands may be viewed as pocket or crevice sites for alkali-metal cations, lined with donor groups to provide ion–dipole interaction and terminated by a hydrophobic methylene chain. The interaction of these ligands with alkali-metal cations has been investigated by spectroscopic techniques and ...
S-block elements are elements that have their valence electrons found on the s-orbital of the element and usually have only one or two valence electrons in their neutral state. The s-block elements are elements that belong to the alkali metal group and the alkaline ...
