Two-armed lariat ethers having double bonds present in their side arms form stable complexes with sodium and potassium cations. When the double bonds are positioned appropriately, cation-π interactions are observed between the neutral double bonds and the macroring- bound cation as demonstrated by X-ray crystallography.
