利用金属-配体结合作为双配位配体自组装聚合的驱动力，为有机/无机杂化材料的制备提供了一条简便的途径。这种金属-超分子聚合物潜在地提供金属离子的官能度沿着聚合物的可加工性。本文中，我们报道了由单体单元制备的凝胶状金属-超分子聚合物的制备，所述单体单元由与镧系金属（例如La（III）、Eu（III））和过渡金属离子（例如Co（II）或Zn（II））混合的连接到聚醚链的任一端的2，6-双-（苯并咪唑基）-4-羟基吡啶单元组成。这种材料对各种刺激，包括热、机械、化学和光，显示出显著的可逆反应。响应的性质可以通过所用过渡金属离子和镧系金属离子的组合的性质来控制。
The use of metal-ligand binding as the driving force for the self-assembly polymerizations of a ditopic ligand offers a facile route to the preparation of organic/inorganic hybrid materials. Such metallo-supramolecular polymers potentially offer the functionality of the metal ion along with the processibility of a polymer. We report, herein, the preparation of gel-like metallo-supramolecular polymers prepared from a monomer unit, which consists of a 2,6-bis-(benzimidazolyl)-4-hydroxypyridine unit attached to either end of a polyether chain, mixed with a lanthanoid metal (e.g. La(III), Eu(III)) and a transition metal ion (e.g. Co(II) or Zn(II)). Such materials show dramatic reversible responses to a variety of stimuli, including thermal, mechanical, chemical and light. The nature of the response can be controlled by the nature of the combination of transition metal ion and lanthanoid metal ion used.
