title: Phenazine-Based Ratiometric Hg2+Probes with Well-Resolved Dual Emissions: A New Sensing Mechanism by Vibration-Induced Emission (VIE).
abstract: Phenazines exhibit intriguing vibration-induced emission (VIE) owing to the fast intrinsic vibration of benzo[a,c]phenazine moiety. For the first time, a phenazine-based ratiometric fluorescent probe DBPST is developed for recognizing Hg2+via restriction of VIE. Upon binding with Hg2+, DBPST demonstrates two well-resolved emission peaks (over 130 nm) with a wide tuning color and affords a large signal-to-background ratio.
