Metalla-aromatic complexes are very stable and excellent light-absorbing compounds, owing to their highly conjugated frameworks. The metallopolymers containing metalla-aromatic substructures consist of a new type of functional polymer, because they exhibit characteristics of both metalla-aromatic and polymeric units. Herein, we reported a corn-like cylindrical metallopolymer, prepared from the controlled polymerization of -isopropylacrylamide (NIPAM) by a polyrotaxane-based macroinitiator, followed by postpolymerization modification with a photothermal metalla-aromatic complex. The corn-like shape of this metallopolymer was confirmed by transmission electron microscopy (TEM). Combining the photothermal effect of the metalla-aromatic unit and the thermosensitive property of PNIPAM, the corn-like metallopolymer exhibits a NIR-responsive behavior and represents a new smart material.
金属芳族配合物由于其高度共轭的骨架，是非常稳定且优异的吸光化合物。含有金属芳族亚结构的金属聚合物由新型功能聚合物组成，因为它们兼具金属芳族单元和聚合物单元的特性。在此，我们报道了一种玉米状圆柱形金属聚合物，它由基于聚轮烷的大分子引发剂对N-异丙基丙烯酰胺（NIPAM）进行可控聚合制备，随后用光热金属芳族配合物进行后聚合修饰。通过透射电子显微镜（TEM）确认了这种金属聚合物的玉米状形状。结合金属芳族单元的光热效应和PNIPAM的热敏性质，这种玉米状金属聚合物表现出近红外响应行为，代表了一种新型智能材料。
