具有精确化学计量比的Fe和Pt原子的位图案化介质（BPM）是未来高面密度磁记录的希望。在这里，我们报告了一种新的含FePt的金属聚合物P作为合成磁性金属合金纳米颗粒的单源前体。该聚合物是由无规共聚物聚苯乙烯-苯乙烯（PES）和二茂铁前体TPy-FePt（[Pt（4′-二茂铁基-（N^N^N））Cl]Cl）通过CuI催化的脱卤化氢反应合成的。P热解后，合成的纳米颗粒中Fe和Pt原子的化学计量比接近1：1，比以TPy-FePt为前驱体的纳米颗粒中Fe和Pt原子的化学计量比更精确。 此外，与TPy-FePt相比，聚合物P更适合于通过高通量纳米压印光刻（NIL）进行图案化。铁磁纳米线，潜在的用于制造位图案化的磁记录介质，成功地从P和充分表征。
Bit-patterned media (BPM) with a precise stoichiometry ratio of Fe and Pt atoms are promising for future high areal density magnetic recording. Here, we report a new FePt-containing metallopolymer P as the single-source precursor for the synthesis of magnetic metal alloy nanoparticles. This polymer was synthesized from a random copolymer poly(styrene-4-ethynylstyrene) PES-PS and the bimetallic precursor TPy-FePt ([Pt(4′-ferrocenyl-(N^N^N))Cl]Cl) by the CuI-catalyzed dehydrohalogenation. After pyrolysis of P, the stoichiometry of Fe and Pt atoms in the synthesized nanoparticles is nearly close to 1 : 1, which is more precise than that by using TPy-FePt as the precursor. Also, polymer P is more suitable for patterning by high-throughput nanoimprint lithography (NIL) compared to TPy-FePt. Ferromagnetic nanolines, potentially useful for fabricating bit-patterned magnetic recording media, were successfully obtained from P and fully characterized.
