Dual‐Channel Gas‐Sensitive Fluorescent Switch: Realizing a Reversible Fluorescent Response to HCl and NH 3

vapor solely via benzene ring locking, and it can likewise be recycled. This study presents the first report of such dual-channel gas-responsive LMOFs. We thoroughly elucidated the underlying mechanisms through experimental work and DFT calculations, paving the way for new advancements in LMOFs-based gas sensing.
