Macrocuclic polyethers having polyethyleneoxy-sidechains extending from a nitrogen pivot bind ammoniumions quite strongly when an 18-memebered ring and a two-oxygen sidechain are present; a 15-memebered ring and other chainlengths give inferior binding.
N-Oligoethylene glycol monoaza crownethers were prepared, and the notable effect of oxyethylene oxygen atoms of the side chain on complexing ability with sodium and potassium cations was confirmed.
