Abstract: The AM1 and INDO/SCI method were used to study supra-molecular complexes composed of octahydroxy calixarenes and monosaccharides and pyrimidine derivatives. It was shown that the host performs a better molecular recognition to mono-saccharides especially to the erythrose by the CH-π interaction but there is almost no π-π interaction between the host and the pyrimidine which exists in the pyrimidine derivative when H is substituted by-COOH, and the "on-off" molecular switching can be designed by this. The reason of red-shift for UV absorption peaks of the complexes compared to that of the host was discussed.

Key words: Calix[4]arenes, Monosaccharides, Pyrimidine, "On-off", molecular switching
