Monitoring of sweat pH plays important roles in physiological health,nutritional balance,psychological stress,and sports perfor-mance.However,the combination of functional MOFs with phosphorescent material to acquire the real-time physiological informa-tion,as well as the application of dual mode anti-counterfeiting,has seldom been reported.Herein,we developed multifunctional gel films based on MOFs and phosphorescent dyes which responded to H+ions and the related mechanism was studied in detail.Upon exposure to H+,the composite gel film exhibited decreased fluorescent signal but enhanced room temperature phosphorescence(RTP),which could be utilized for sweat pH sensing through a dual-mode.Moreover,multifunctional gel films exhibited a potential ap-plication in information encryption and anti-counterfeiting by designing of stimulus responsive multiple patterns.This research pro-vided a new avenue for portable and non-invasive sweat pH monitoring methods while also offering insights into stimulus-responsive multifunctional materials.
