Abstract

Metal-organic frameworks (MOFs) have garnered considerable attention as exceedingly promising materials recently due to their enduring porosity and adaptable host-guest interactions. Over the past few decades, extensive investigations have been dedicated to the synthesis and diverse applications of MOF materials, encompassing, yet not restricted to, gas storage and separation, sensing, and catalysis. In addition, photoluminescence in MOFs has emerged as a significant area of interest. Herein, we provide an in-depth insight into the origins and fundamentals of MOF photoluminescence, which include basic concepts of photoluminescence and main mechanisms that depict the photoluminescence in MOFs (ligand-centered, metal-centered, ligand-to-metal charge transfer, metal-to-ligand charge transfer, and guest induced). Besides, our review also delineates a perspective to design MOFs and their composites by tuning fluorescent ligands and metal centers, and incorporating fluorescent guest molecules, which are highly beneficial for sensing, white-light emission, optical information protection, and so forth. In addition, the current challenges and promising research directions are pinpointed.

期刊介绍: Coordination Chemistry Reviews offers rapid publication of review articles on current and significant topics in coordination chemistry, encompassing organometallic, supramolecular, theoretical, and bioinorganic chemistry. It also covers catalysis, materials chemistry, and metal-organic frameworks from a coordination chemistry perspective. Reviews summarize recent developments or discuss specific techniques, welcoming contributions from both established and emerging researchers. The journal releases special issues on timely subjects, including those featuring contributions from specific regions or conferences. Occasional full-length book articles are also featured. Additionally, special volumes cover annual reviews of main group chemistry, transition metal group chemistry, and organometallic chemistry. These comprehensive reviews are vital resources for those engaged in coordination chemistry, further establishing Coordination Chemistry Reviews as a hub for insightful surveys in inorganic and physical inorganic chemistry.
