Responsive luminescent MOF materials for advanced anticounterfeiting

Smart stimuli-responsive luminescent metal–organic frameworks (MOFs), combining the unique advantages and exciting application prospects, have gained booming development in recent years. The powerful capability to respond the external chemical or physical stimuli through various manners makes them particularly attractive in anti-counterfeiting technologies. This review aims at the recent progress of the stimuli-responsive luminescent MOF materials for advanced anti-counterfeiting technologies. The representative types of stimuli, such as light, temperature, solvent, pH, ion are summarized. In addition, the responsive luminescence and mechanisms, and the implementation strategies for advanced anti-counterfeiting are discussed. We also briefly present the current challenges and future perspectives of stimuli-responsive luminescent MOF materials for anticounterfeiting application. We hope this review would provide some new insights and guidelines for the design and engineering of novel stimuli-responsive luminescent MOF materials for advanced anticounterfeiting and information encryption.
