ABSTRACT
Covalent organic frameworks (COFs) represent an emerging class of crystalline porous polymers characterized by their pre-designed interconnected structures formed via dynamic covalent bonds. These materials have garnered widespread attention in recent years. While applications two-dimensional (2D) COFs been extensively investigated since 2005, practicality has impeded limited specific surface area and the robust π-π stacking interaction. In contrast, three-dimensional (3D) boast enhanced porosity, larger area, well-exposed functional groups, abundance reaction sites, positioning them at forefront material research. They find extensive diverse fields, including adsorption, separation, catalysis, so on. This featured article provides a comprehensive exploration latest advancements 3D across respective application domains. Additionally, we outline current challenges that must be addressed shed light on promising prospects for utilization COFs.
