Conjugated polyimines constructed from aromatic amines and aromatic aldehydes have attracted enormous attention because of their excellent and fascinating properties. However, the structure of these materials constructed by building blocks or linkers is usually confined to a scope of microporosity and small mesopores (less than 5 nm), which largely impedes their applications in many fields. Here, a facile self‐assembly strategy is developed to controllably fabricate conjugated polyimines nanospheres with multichambered mesoporous architecture by using polystyrene‐b‐poly(acrylic acid) diblock copolymer as a soft template. Given the wide availability of amines and aldehydes, it is expected to open new avenues for designing diverse polyimine‐based materials with controlled mesostructure toward applications.

嵌段共聚物指导的多腔介孔共轭聚亚胺纳米球的合成

由芳族胺和芳族醛构成的共轭聚亚胺因其优异而引人入胜的性能而备受关注。然而，这些由结构单元或连接基构成的材料的结构通常局限于微孔和小中孔（小于5 nm）的范围，这极大地阻碍了它们在许多领域中的应用。在这里，开发了一种简便的自组装策略，以聚苯乙烯-b-聚（丙烯酸）二嵌段共聚物为软模板，可控制地制造具有多室介孔结构的共轭聚亚胺纳米球。鉴于胺和醛的广泛应用，有望为设计各种介孔结构受控的聚亚胺基材料开辟新途径。
