摘要: 用AM1和INDO/SCI方法对八羟基杯[4]芳烃与单糖及嘧啶衍生物形成的超分子体系进行理论研究,结果表明,主体通过CH-π相互作用对单糖类进行分子识别,尤其对赤藓糖识别效果更好;主体与嘧啶没有明显的π-π堆砌作用,但能识别含吸电子基团的嘧啶衍生物,据此可设计酸碱调控的分子开关.讨论了配合物的UV谱带与主体相比发生红移的原因.

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
