Abstract
Crystalline complexes of composition 1:1 of calixresorcinarenes 1 and 2, and crown ether 3, with a number of benzene derivatives have been synthesized. 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 calixresorcinarenes 1 and 2 exist in the boat conformation both in the solid state and in solution. The guest molecules in complexes of calixresorcinarenes 1 are located within channels in the host crystal lattice. The selectivity of binding of benzene derivatives was investigated and the role of the hydrogen bonds and CH … π interaction was estimated.Keywords
