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.
