About this collection
Metal-organic frameworks (MOFs), comprised of metal ions and bridging organic ligands, have emerged as an important family of porous materials. Owing to their highly porous structures with functional properties, MOFs are considered as one of the most ideal materials for chemical sensors as the sensing properties are strongly influenced by surface interaction between analyte molecules and pore walls of MOFs. The application of MOFs covers the fields of sensing toward a variety of target compounds, including gases, solvents, explosives, ions, pollutions, and biological molecules. This spotlight collection focuses on the latest studies on MOF-based sensors published in Dalton Transactions, showing highly sensitive detections and the future research directions using MOFs with respect to general sensing principles and analytical performance.
