Abstract(s)

Hydrazine (N2H4) and ClO− are very harmful for public health, hence it is important and necessary to monitor them in living cells. Herein, we rationally designed and synthesized a dual-analytes responsive fluorescent sensor PTMQ for distinguishing detection of N2H4 and ClO−. PTMQ underwent N2H4-induced double bond cleavage, affording colorimetric and green fluorescence enhancement with good selectivity and a low detection limit (89 nM). On the other hand, PTMQ underwent ClO−-induced sulfur oxidation and displayed red fluorescence lighting-up response towards ClO− with good selectivity, rapid response (<0.2 min) and a low detection limit (58 nM). Moreover, PTMQ was successfully employed for in-situ imaging of N2H4 and ClO− in living cells
