Title

Gas Phase Structures of Cryptand-Metal Ion Complexes

Abstract

Cryptands are a family of polycyclic multidentate ligands for various cations. Having greater selectivity and binding strength than other ligands, cryptands have been studied fort their ability to catalyze the phase transfer of insoluble salts into organic solvents. Cryptands also have the potential to be used in the cleanup of heavy radioactive alkali metals such as cesium-137. In this study we use a Fourier Transform based mass spectrometer to measure the novel properties of gas-phase cryptand-metal complexes. We are also interested in evaluating the capability of molecular mechanics calculations in accurately describing the geometries of cryptand-metal complexes. The results of this study will greatly aid in the continued study and synthesis of cesium-selective cryptand molecules.
