Gases have played a crucial role in various industries, spanning from manufacturing and medicine to electronics. In these industries, the attainment of pure gases through effective separation methods has been recognized as essential. Porous materials-based adsorption and separation technologies have garnered significant attention due to their advantageous features, including low energy consumption and simplified operational procedures. Among these materials, porous organic cages (POCs) have emerged as a promising class, constructed by individually designed macromolecules possessing inherent cavities that are tailor-made, soluble, easily regenerated, and amenable to precise modifications. Analogous to well-established porous framework materials like zeolites, metal–organic frameworks (MOFs), and covalent organic frameworks (COFs), POCs have exhibited their intrinsic potential for gas separation applications in recent years. In this review, we delve into the progress achieved in the realm of POCs, with a particular focus on their utilization for selective gas separation. Moreover, we present an outlook on the future prospects of this field, along with the existing challenges that demand further attention.

用于气体分离的多孔有机笼

气体在从制造、医药到电子等各个行业中发挥着至关重要的作用。在这些行业中，通过有效的分离方法获得纯净气体已被认为是至关重要的。基于多孔材料的吸附和分离技术因其低能耗和简化操作程序等优点而受到广泛关注。在这些材料中，多孔有机笼（POC）已成为一类很有前途的材料，它由单独设计的大分子构成，具有定制的、可溶的、易于再生且易于精确修饰的固有空腔。类似于沸石、金属有机框架（MOF）和共价有机框架（COF）等成熟的多孔框架材料，近年来，POC 在气体分离应用中展现出了其内在潜力。在这篇综述中，我们深入研究了 POC 领域取得的进展，特别关注其在选择性气体分离中的应用。此外，我们对该领域的未来前景以及需要进一步关注的现有挑战进行了展望。
