Herein we report a universal method for the preparation of multifunctional hollow microporous organic nanospheres (H-MONs) using functional aromatic monomers (such as benzylamine, 2,2-bipyridine, triphenylamine or carbazole) and the polylactide-b-polystyrene (PLA-b-PS) diblock copolymer as precursors based on a one-pot hyper-cross-linking mediated self-assembly strategy. In this method, co-hyper-cross-linking among the PS block and various aromatic monomers forms the functional microporous organic shell frameworks, while the degradable PLA block produces the hollow core structure. By introducing functional organic ligands, various metal-loaded or heteroatom-doped H-MONs can be successfully synthesized. Owing to their high special surface area, robust organic framework, and hierarchically porous structure, these multifunctional H-MONs exhibited excellent catalytic activity or high adsorption capacity for radioactive iodine. The proposed one-pot strategy may provide a general approach to produce a variety of functional H-MONs for various applications in the future.

通过一锅超交联介导的自组装策略 制备多功能中空微孔有机纳米球†

本文中，我们报告了一种使用功能性芳香族单体（如苄胺，2,2-联吡啶，三苯胺或咔唑）和聚丙交酯-b-聚苯乙烯（PLA- b）制备多功能中空微孔有机纳米球（H-MONs）的通用方法-PS）双嵌段共聚物作为前体，基于一锅超交联介导的自组装策略。在这种方法中，PS嵌段与各种芳族单体之间的超交联形成了功能性的微孔有机壳骨架，而可降解的PLA嵌段则产生了中空的核结构。通过引入功能性有机配体，可以成功合成各种负载金属或掺杂杂原子的H-MON。由于它们的高比表面积，坚固的有机骨架和分层多孔结构，这些多功能H-MONs表现出出色的催化活性或对放射性碘的高吸附能力。拟议的一锅策略可能会提供一种通用方法，以在将来为各种应用生产各种功能性H-MON。
