The double-calixcrown (1) was shown to form 1: 1 complexes with potassium and rubidium picrates in the solid state and in solution in chloroform. The stability constants of the alkali complexes have been determined in acetonitrile, as well as the phase transfer parameters from water to dichloromethane.
