摘要

A set of three-armed urea-containing anion receptors was prepared. The receptors all have the same binding topology but differ in the level of conformational preorganisation with respect to the arrangement of the side-arms relative to the platform and within the side arms themselves. This is mirrored in a specific increase (X 2.5) in the binding constant for chloride and in a 12-fold increase in the chlorideitrate-selectivity.
