Abstract

Abstract: Polyaza-receptors 1-3 and pyridine were investigated as complexing agents for phosphoric acid diesters in chloroform. These receptors were used to determine the optimum cavity size for complexing phosphoric acid diesters and to measure the strength of interactions formed by individual host hydrogen bond donors and acceptors. Inflections in either the 3lP or IH NMR isotherms were found for all receptors. The NMR data indicate ...
