Abstract

Cage-type molecules composed of phenyl walls and caps were synthesized as hosts for the binding of ammonium and alkali metal cations through cation-π interactions. The synthesis involved a key cyclization step, which was markedly dependent on the capping component. Binding studies by electrospray ionization mass spectrometry toward lithium, sodium, potassium, and ammonium cations showed that the cage-type molecules selectively form ...
