Synthesis of coordination polymers which show functions based on the tube type channels.

采用两种方法构建管状通道；一种是通过金属配合物与分子间氢键的连接，另一种是通过1D聚合物配合物的组装。前一种化合物表现出通道结构的坍塌和重建，以响应甲醇的去除和重新接触，甲醇是管框架的组成部分。特别地，该函数对于添加甲醇诱导的较大客体分子的吸附是有用的。后一种化合物显示出响应温度变化的可逆管状通道结构变化。其相变特性取决于通道中金属离子和客体分子的种类。

Tube-like channels were constructed by two methods ; one was by connections of metal complexes with intermolecular hydrogen bonds, and the other was by assemblies of 1D polymer complexes. The former compound showed collapse and reconstructions of the channel structures responding to the removal and re-contact of methanol, which was a part of building block of the tube frameworks. Particularly, this function was useful for adsorption of larger guest molecules induced by addition of methanol. The latter compound showed reversible structural changes of the tube-like channels responding to temperature-variation. The phase-transition properties were dependent on kinds of metal ions and guest molecules in the channels.
