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 mu M. 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-.
