Core–shell structured magnetic mesoporous polymer or carbon‐based microspheres not only possess the combined merits of magnetic particles and stable mesoporous shell but also provide various organic functional groups for further modification and immobilization of active sites, thus opening up more possibility for various applications. Herein, a bottom‐up soft‐templating strategy is developed to controllably synthesize core–shell magnetic mesoporous polydopamine microspheres (MMP) and their derivative magnetic mesoporous carbon (MMC) microspheres via an amphiphilic block copolymer‐directed interface assembly and polymerization (denoted as abc‐DIAP) approach. The obtained uniform MMP microspheres have a well‐defined structure consisting of magnetic core, silica middle layer and mesoporous PDA shell, uniform mesopores of 11.9 nm, high specific surface areas (235.6 m² g⁻¹) and rich functional groups. They show fast magnetic separation speed and superior performance in selective adsorption of Cyt.C from complex biosample solutions. Moreover, they can be in situ converted into core–shell magnetic mesoporous carbon (MMC) for efficient in‐pore immobilization of ultrafine Au nanoparticles for high‐efficiency catalytic epoxidation of styrene with high conversion (88.6%) and selectivity (90.1%) toward styrene oxide.

磁性胶体的界面共组装和聚合：核壳功能介孔聚合物微球及其碳衍生物。

核壳结构的磁性介孔聚合物或碳基微球不仅具有磁性颗粒和稳定介孔壳的综合优点，而且还提供各种有机官能团以进一步修饰和固定活性位点，从而为各种应用开辟了更多可能性。在此，开发了一种自下而上的软模板策略，通过两亲性嵌段共聚物引导的界面组装和聚合（表示为 abc）可控地合成核壳磁性介孔聚多巴胺微球（MMP）及其衍生的磁性介孔碳（MMC）微球‐DIAP）方法。所得均匀的MMP微球具有由磁芯、二氧化硅中间层和介孔PDA壳组成的清晰结构，均匀的介孔尺寸为11.9 nm，高比表面积（235.6 m ² g ^-1）和丰富的官能团。它们在从复杂的生物样品溶液中选择性吸附 Cyt.C 方面表现出快速的磁分离速度和卓越的性能。此外，它们可以原位转化为核壳磁性介孔碳（MMC），用于有效孔内固定超细金纳米粒子，用于苯乙烯的高效催化环氧化，具有高转化率（88.6％）和选择性（90.1％）氧化苯乙烯。
