Macrocyclic polyethers as probes to assess and understand alkali metal cation-π interactions

Cation-π interactions of alkali metals with arenes have been known in the gas phase for two decades but solid-state structural data have become available only recently. The quest for solid-state evidence is described here. Complexation of Na + and K + by arene-terminated lariat ethers has provided i...

Description
Summary:Cation-π interactions of alkali metals with arenes have been known in the gas phase for two decades but solid-state structural data have become available only recently. The quest for solid-state evidence is described here. Complexation of Na + and K + by arene-terminated lariat ethers has provided important insights into the cation-π interaction.
