Abstract
A new cyclometalated iridium(III) complex-based fluorescence probe (IrCN) for hypochlorite (ClO−) has been synthesized and characterized. The probe displayed nonfluorescent around 577 nm, while a 54-fold enhancement in fluorescence emission intensity was observed after the addition of ClO− due to the removal of C=N isomerization effect. Such “turn-on” fluorescence probe worked excellently in wide pH range (5–12) with short response time (<20 s) and the detection limit was as low as 0.11 μM. In addition, IrCN exhibited high selectivity towards ClO− even in the presence of other competing species. Furthermore, IrCN was successfully integrated in fluorescent test strips for real-time detection of ClO−.
