Molecular Paneling in the Rational Design of Calixarene Coordination Polymers

We
demonstrate the design of calixarene coordination polymers by
using versatile molecular panels comprising binuclear Co­(II) clusters
and p-carboxylatocalix­[4]­arenes linked together with
4,4′-bipyridyls. By variation in the length of the 4,4′-bipyridyl,
conformational changes in the calixarene molecule have been observed
and the solvent-filled channels within the crystalline solid have
been adjusted.

本研究展示了杯芳烃配位聚合物（calixarene coordination polymers）的设计方案：采用由双核钴(II)簇（binuclear Co(II) clusters）与对羧基杯[4]芳烃（p-carboxylatocalix[4]arenes）构成的多功能分子模块，并通过4,4'-联吡啶（4,4′-bipyridyls）实现模块间的连接。通过改变4,4'-联吡啶的链长，我们观测到杯芳烃分子发生构象变化，并对晶体材料内部的溶剂填充孔道进行了调控。
