A terpyridine-Zn²⁺ complex TpyZnS was synthesized and developed as a turn-off fluorescent probe for HClO in aqueous solution. The fluorescence intensity of TpyZnS dramatically decreased within 10 seconds in the presence of HClO. Additionally, the detection limit for HClO was found to be 0.16 μM. It is proposed that oxidation of the thioether group in TpyZnS to the corresponding sulfoxide is probably responsible for the fluorescence quenching of TpyZnS. The possible sensing process was studied by ¹H NMR, HRMS spectroscopy and theoretical calculations. Finally, the probe TpyZnS was successfully employed in the detection of HClO in real water samples and bioimaging.

基于三联吡啶-Zn ²⁺络合物的快速响应荧光探针，用于感测水溶液中的次氯酸及其在实际水样和生物成像中的应用†

合成并合成了一个吡啶吡啶-Zn ²⁺复合物TpyZnS，作为水溶液中HClO的截止荧光探针。在HClO存在下，TpyZnS的荧光强度在10秒内急剧下降。另外，发现HClO的检出限为0.16μM。建议将TpyZnS中的硫醚基氧化为相应的亚砜可能是TpyZnS的荧光猝灭的原因。通过¹ H NMR，HRMS光谱和理论计算研究了可能的传感过程。最后，探针TpyZnS 已成功用于实际水样品和生物成像中HClO的检测。
