In recent years, metallopolymers have attracted much attention as precursors to generate magnetic metal/metal alloy nanoparticles (NPs) through pyrolysis or photolysis because they offer the advantages of ease of solution processability, atomic level mixing and stoichiometric control over composition. The as-generated NPs usually possess narrow size distributions with precise control of composition and density per unit area. Moreover, patterned NPs can be achieved on various substrates in this way owing to the good film-forming property of metallopolymers and such work is important for many applications based on metal nanostructures. By combining the merits of both the solution processability of metallopolymers and nanoimprint lithography (NIL), a new platform can be created for fabricating bit-patterned media (BPM) and the next-generation of nanoscale ultra-high-density magnetic data storage devices. Furthermore, most of these metallopolymers can be used directly as a negative-tone resist to generate magnetic metallic nanostructures by electron-beam lithography and UV photolithography. Self-assembly and subsequent pyrolysis of metalloblock copolymers can also afford well-patterned magnetic metal or metal alloy NPs in situ with periodicity down to dozens of nanometers. In this review, we highlight the use of metallopolymer precursors for the synthesis of magnetic metal/metal alloy NPs and their nanostructures and the related applications.

一种由金属聚合物前体制备磁性金属纳米结构的分子方法

近年来，金属聚合物作为通过热解或光解产生磁性金属/金属合金纳米颗粒（NP）的前体引起了广泛的关注，因为它们具有易于溶液加工，原子级混合和化学计量控制组成的优势。刚生成的NP通常具有窄的尺寸分布，并且精确控制每单位面积的组成和密度。而且，由于金属聚合物的良好的成膜性能，可以通过这种方式在各种基板上获得图案化的NP，并且这种工作对于基于金属纳米结构的许多应用是重要的。通过结合金属聚合物的溶液可加工性和纳米压印光刻技术（NIL）的优点，可以创建一个新平台来制造位模式媒体（BPM）和下一代纳米级超高密度磁数据存储设备。此外，这些金属聚合物中的大多数可直接用作负型抗蚀剂，以通过电子束光刻和UV光刻产生磁性金属纳米结构。金属嵌段共聚物的自组装和随后的热解也可以提供结构良好的磁性金属或金属合金NP原位周期低至几十纳米。在这篇综述中，我们重点介绍了金属聚合物前体在磁性金属/金属合金纳米颗粒及其纳米结构及其相关应用中的应用。
