“…Good biocompatibility, sufficient stability, and interesting bioimaging behaviors were some of the unique features of the reported system. In a recent work, Bian et al 906 assessed the NIR imaging efficiency of nanoprobes based on Pt/Pdcontaining metallopolymers. Due to the favorable probe size, they showed good biocompatibility and specificity to HeLa cancer cells.…”

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.

A novel heterometallic Zn‐/Co‐porphyrin conjugated polymer (ZnCoP‐F CP) with its Co‐porphyrin bridging unit bearing two perfluorophenyls is synthesized via a Sonogashira coupling reaction. The resulting ZnCoP‐F CP without the Pt cocatalyst exhibits broadband (UV–vis–NIR) light‐driven hydrogen evolution activity of 83 µmol h−1, which is more than twice that (39 µmol h−1) of its counterpart (ZnCoP CP) with the Co‐porphyrin unit bearing two phenyls. Furthermore, an apparent quantum yield of 6.92%, 5.50%, 5.78%, 3.17%, and 0.73% is achieved from the ZnCoP‐F CP illuminated at 400, 500, 550, 700, and 850 nm monochromatic light, respectively. The enhanced performance of ZnCoP‐F CP can be attributed to the high electron‐withdrawing capacity of its perfluorophenyls and the highly dispersed Co centers in Co‐porphyrin bridging units serving as single‐atom catalytic sites (CoN4), which facilitate the formation of periodic type II‐like heterojunctions and the fast charge transfer from Zn‐porphyrin to Co‐porphyrin units for hydrogen evolution reaction. The broadband‐responsive feature is due to the large π‐conjugated system through the whole 2D internal framework of the porphyrin polymer. This work opens a new path to fabricate porphyrin‐based polymer with an efficient and broadband‐responsive hydrogen evolution system.
