INCLUSION-COMPOUNDS OF OCTAKIS-DIPHENOXY-PHOSPHORYLOXY-, OCTAKIS-TOSYLOXYTETRA METHYLCALIX[4] RESORCINARENES AND BIS-(DIISOPROPOXYPHOSPHORYL) DIBENZO-18-CROWN-6 WITH BENZENE-DERIVATIVES

Crystalline complexes of composition 1:1 of calixresorcinarenes 1 and 2, and crown ether 3, with a number of benzene derivatives have been s ynthesized. By means of X-ray crystallography and NMR-spectroscopy the structures of the host molecules and the complexes in the solid state and solutions have been investigated. It was shown that calixresorcin arenes 1 and 2 exist in the boat conformation both in the solid state and in solution. The guest molecules in complexes of calixresorcinaren es 1 are located within channels in the host crystal lattice. The sele ctivity of binding of benzene derivatives was investigated and the rol e of the hydrogen bonds and CH ...pi interaction was estimated.
