Abstract
Equilibrium constants and enthalpies of host-guest complexation have been determined by calorimetry for cyclic and acyclic polyether hosts with a variety of guests and solvents. The thermodynamic parameters for complexation of group I cation guests by crown ethers in water solvent may be correlated to the hydration enthalpy and relative sizes of cation and ether. The macrocyclic effect is observed for cation-ether systems in water solvent but not for the complexation of malononitrile by ethers in nonpolar aromatic or alcohol solvent.
