| Abstract: | We developed a new fluorescent sensor (PPC-S) for Hg2+ based on the aggregation-induced emission (AIE) of pyrazolo3,4-b]pyridine-based coumarin chromophore (PPC-O). Given the desulfurization reaction with Hg2+, AIE inactive PPC-S can be transformed into PPC-O with AIE activity, which can be employed for the fluorescence turn-on detection of Hg2+ with satisfactory selectivity and sensitivity in aqueous solutions. |
