Supramolecular complexes of podand ligands with xenon

Abstract

Formation of stable complexes between xenon and podand polyoxyethylene ligands was ascertained. The complexation process was studied by 129Xe NMR titration, NMR diffusiometry and heteronuclear NOE measurements. The ligands studied form a 1:1 complexes with Xe(0). Their stability constants depend on the ligand structure, i.e., polyoxyethylene chain length, number of complexating polyether units and the topology of the anchoring centre.
