本文提出了一种正交自组装方法，通过二烷基仲铵盐与冠醚基团之间的Pt···Pt/π-π相互作用和主客体识别，将平面铂配合物与星形聚ε-己内酯偶联，制备了一系列金属超分子聚合物.固体金属超分子聚合物表现出亚10 nm尺度的层状结构，其中之一占据了非凡程度的长程有序。铂（II）配合物可以被视为一个单独的超分子块的微相分离的聚合物段。此外，金属超分子聚合物显示出强烈的发光和可观的质子导电性，分别源于这两种超分子连接模式。该工作为制备具有高度有序纳米结构和多功能性质的金属超分子聚合物铺平了道路。
We here present an orthogonal self-assembly strategy to fabricate a series of metallosupramolecular polymers by coupling planar platinum(II) complexes and starlike poly(ε-caprolactone), through Pt···Pt/π–π interactions and host–guest recognition between secondary dialkylammonium salts and crown ether groups. The solid metallosupramolecular polymers exhibit sub-10 nm scale lamellar structures and one of them occupies an extraordinary degree of long-range order. The platinum(II) complexes can be regarded as an individual supramolecular block to microphase segregate the polymeric segment. Moreover, the metallosupramolecular polymers show intense luminescence and appreciable proton conductivity, originating from these two supramolecular connection modes, respectively. This work paves the way for fabricating metallosupramolecular polymers showing both highly ordered nanostructures and multifunctional properties.
