CO, an acidic gas, is usually emitted from the combustion of fossil fuels and leads to the formation of acid rain and greenhouse effects. CO can be used to produce kinds of value-added chemicals from a viewpoint based on carbon capture, utilization, and storage (CCUS). With the combination of unique structures and properties of ionic liquids (ILs) and covalent organic frameworks (COFs), covalent organic frameworks with ionic liquid-moieties (ILCOFs) have been developed as a kind of novel and efficient sorbent, catalyst, and electrolyte since 2016. In this critical review, we first focus on the structures and synthesis of different kinds of ILCOFs materials, including ILCOFs with IL moieties located on the main linkers, on the nodes, and on the side chains. We then discuss the ILCOFs for CO capture and conversion, including the reduction and cycloaddition of CO. Finally, future directions and prospects for ILCOFs are outlined. This review is beneficial for academic researchers in obtaining an overall understanding of ILCOFs and their application of CO conversion. This work will open a door to develop novel ILCOFs materials for the capture, separation, and utilization of other typical acid, basic, or neutral gases such as SO, HS, NOx, NH, and so on.
一氧化碳是一种酸性气体，通常由化石燃料燃烧产生，会导致酸雨形成和温室效应。从碳捕获、利用和储存（CCUS）的角度来看，一氧化碳可用于生产各种增值化学品。自2016年以来，随着离子液体（ILs）和共价有机框架（COFs）独特的结构和性能相结合，带有离子液体部分的共价有机框架（ILCOFs）已被开发成为一种新型高效的吸附剂、催化剂和电解质。在这篇综述中，我们首先关注不同类型的ILCOFs材料的结构和合成，包括离子液体部分位于主连接体、节点和侧链上的ILCOFs。然后我们讨论用于一氧化碳捕获和转化的ILCOFs，包括一氧化碳的还原和环加成。最后，概述了ILCOFs的未来发展方向和前景。这篇综述有助于学术研究人员全面了解ILCOFs及其在一氧化碳转化中的应用。这项工作将为开发用于捕获、分离和利用其他典型酸性、碱性或中性气体（如二氧化硫、硫化氢、氮氧化物、氨气等）的新型ILCOFs材料打开一扇门。
