Abstract

A macrocyclic malonic ester condensation with pyridine building blocks leads to the new bicyclic host molecule 1 with defined cavity size, the X-ray structure analysis of which reveals three convergent nitrogen donor centres; in radiotracer phase-transfer measurements 1 turns out to be remarkably selective for AgI cations while discriminating against CuI and CuII cations.
