Potential 129Xe-NMR biosensors based on secondary and tertiary complexes of a water-soluble pillar[5]arene derivative

Abstract

We report on the first secondary and tertiary complexes of the pillar[5]arene derivative with xenon in water. We show that the chemical shift of the encapsulated xenon provides information on the type of the formed complex suggesting that has the potential to be used as a platform for NMR biosensors.
