“…However, they are hard to process. Methods to obtain defect-free membranes from these materials have been developed, such as interfacial polymerization based on the interface-confined reaction, the macromolecular-mediated crystallization approach, the chemical vapor deposition approach, aqueous sol–gel synthesis, etc. However, improvement/updates of these methods are still needed to meet the demand for fabricating large-area and self-standing membranes.…”

Ion exchange membranes allowing the passage of charge-carrying ions have established their critical role in water, environmental, and energy-relevant applications. The design strategies for high-performance ion exchange membranes have evolved beyond creating microphase-separated membrane morphologies, which include advanced ion exchange membranes to ion-selective membranes. The properties and functions of ionselective membranes have been repeatedly updated by the emergence of materials with subnanometer-sized pores and the understanding of ion movement under confined micropore ion channels. These research progresses have motivated researchers to consider even greater aims in the field, i.e., replicating the functions of ion channels in living cells with exotic materials or at least targeting fast and ion-specific transmembrane conduction. To help realize such goals, we briefly outline and comment on the fundamentals of rationally designing membrane pore channels for ultrafast and specific ion conduction, pore architecture/chemistry, and membrane materials. Challenges are discussed, and perspectives and outlooks are given.

“…Moreover, good solubility, a unique characteristic of POCs, will, in turn, be adverse to POC recycling in specific applications. On the other hand, porous framework materials, such as porous organic polymers (POPs) [16][17][18][19] , covalent organic frameworks (COFs) [20][21][22][23][24] , metal-organic frameworks (MOFs) [25][26][27][28] , and supramolecular organic frameworks (SOFs) [29][30][31][32] , have attracted the attention of researchers due to their large surface area, adjustable porosity, outstanding robustness, and facile post-modification. Hence, the marriage of POCs and framework materials might give rise to task-specific organic cage-based frameworks (OCFs) with fascinating structures and exceptional performance, which not only overcome the defects of POCs but also inherit the merits of various framework materials.…”

The investigation of organic cage-based frameworks (OCFs) has attracted increasing attention over the past decade due to their versatile synthetic methods and broad property range resulting from the unique combination of porous organic cages (POCs) with diverse framework materials, including porous organic polymers (POPs), metal-organic frameworks (MOFs), and supramolecular organic frameworks (SOFs). Nevertheless, a comprehensive summary of the research advancements in OCFs remains elusive in the literature. This review addresses this gap by providing a detailed overview of the development of OCF-based materials from both synthetic and applicative perspectives. The discussion begins with systematically exploring design principles and common strategies for elaborating OCFs, achieved by rational selection of bond-forming routes suitable for various POC monomers, including covalent bonds, coordination bonds, and supramolecular interactions. Subsequently, the review highlights the functional attributes derived from the distinctive structural features of OCFs, showcasing their task-specific applications in adsorption/separation, catalysis, membrane technology, and other fields. Lastly, the article summarizes the opportunities and challenges anticipated as the exploration of the OCF family continues to advance in material science.
