Hierarchically porous materials have attracted great attention because of their potential applications in the fields of adsorption, catalysis, and biomedical systems. The art of manipulating different templates that are used for pore construction is the key to fabricating desired hierarchically porous structures. In this feature article, the polyelectrolyte-surfactant mesomorphous complex templating (PSMCT) approach, which was first developed by our group, is elaborated on. During the organic-inorganic self-assembly, the mesomorphous complex of the polyelectrolyte and oppositely charged surfactants would undergo in situ phase separation, which is the key to fabricating hierarchically porous materials. The recent progress in the utilization of the PSMCT method for the synthesis of hierarchically porous materials with tunable morphologies, mesophases, pore structures, and compositions is reviewed. Meanwhile, the functions of the hierarchically porous materials synthesized by the PSMCT method and their applications in adsorption, catalysis, drug delivery, and nanocasting are also briefly summarized.
多级孔材料因其在吸附、催化和生物医学系统等领域的潜在应用而备受关注。操纵用于孔构建的不同模板的技术是制造所需多级孔结构的关键。在这篇专题文章中，详细阐述了我们小组首次开发的聚电解质-表面活性剂介晶复合物模板法（PSMCT）。在有机-无机自组装过程中，聚电解质和带相反电荷的表面活性剂的介晶复合物会发生原位相分离，这是制备多级孔材料的关键。综述了利用PSMCT方法合成具有可调形态、中间相、孔结构和组成的多级孔材料的最新进展。同时，也简要总结了通过PSMCT方法合成的多级孔材料的功能及其在吸附、催化、药物递送和纳米铸造中的应用。
