The synthesis as well as the clathration properties of cyclophanes containing the chiral spirobiindanol phosphonate moiety is reported. Macrocycles have been synthesized in satisfactory yields by a two steps procedure. NMR spectroscopy reveals that in solution these compounds are arranged in a dissymetric structure (point group symmetry C2) with a great conformational mobility. By recrystallization of macrocycles from a mixture of cyclohexane and other organic solvents was found that all of them are able to form inclusion complexes only with cyclohexane. The crystal and molecular structure of one of them has benn determined by single crystal X-ray analyses.
