Abstract

AbstractEight new macrocyclic polyether ligands containing the proton‐ionizable triazole subcyclic unit have been prepared. Most of these compounds contain octyl, benzo or cyclohexano lipophilic groups. The unsubstituted triazolo‐18‐crown‐6 (5) formed an unusual complex with silver ion. The crystal structure of this silver complex showed one crown complexed with one silver cation and two associated silver nitrate molecules. The new lipophilic triazolo‐crowns are being tested as cation carriers for alkali and other metal cations in a bulk liquid membrane system.
