摘要
本文利用X射线衍射法研究了四羟基杯[4]芳烃与水、氯仿的包合物的晶体结构,它们属六方晶系,为分子间包合物。通过这些研究发现:在晶体中,四羟基杯[4]芳烃是通过六重螺旋轴的作用形成一种管道型的空间来包合客体分子,这种管道具有对客体分子选择性等特点。
The crystal structure of tetrahydroxycalix[4]arene clathrate with water or chloroform was determined by X-ray diffraction analysis. They belong to hexagonal system, and the both are intermolecular clathrate. The results indicate that a tubular space is formed from tetrahydroxycalix[4]arene through hexad axis rotation to tnclude the guest molecule, and this tubulator possesses selective and other properties for the guest molecule.
