Abstract

Monitoring of sweat pH play important roles in physiological health, nutritional balance, psychological stress, and sports performance. The combination of functional MOFs with phosphorescent material to acquire the real-time physiological information, as well as the ap-plication of dual mode anti-counterfeiting, have seldom been reported. Herein, we reported MOF and phosphorescent dyes based mul-tifunctional gel films with H+ response and the related mechanism was studied in detail. Upon induction of H+, the composite gel film ex-hibited 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 application in information encryption and an-ti-counterfeiting by designing of stimulus responsive multiple patterns. This research opens a new avenue for portable and non-invasive sweat pH monitoring method, provides opportunities for effective anti-counterfeiting, also offers new insights stimulus-responsive mul-tifunctional materials and their potential applications.
