Description
Summary:Two‐dimensional (2D) MXene has aroused wide attention for its excellent physical and chemical properties. The interlayer engineering formed by layer‐by‐layer stacking of MXene nanosheets can be employed for molecular sieving and water purification by incorporating specific groups onto the exterior surface of MXene. Macrocyclic hosts exhibiting unique structural features and recognition ability can construct smart devices for external stimuli with reversible features between macrocycles and guests. On that basis, macrocyclic hosts can be anchored to MXene to provide numerous insights into their compositions and intercalation states. In this review, the MXene prepared based on macrocyclic hosts from molecular design to applications is highlighted. Various MXenes functionalized with macrocyclic hosts are empowered in functional membrane (including water purification, organic solvent nanofiltration, and electromagnetic shielding), photocatalysis, sensing, and adsorption (interactions with specific guest). Hopefully, this review can bring new inspiration to the design of multifunctional MXene‐based materials and improving its practical applications. Developments of hybrid MXene functionalized with macrocyclic hosts in the fields of functional membranes, photocatalysis, sensing, adsorption and separation are discussed in this review article, which aims to summarize the research in a way to aid the future design of hybrid MXene nanomaterials with satisfied capabilities in the fields of membrane technology and intelligent devices.
