A new phenanthroimidazole-based fluorescence probe for selective detection of HClO was synthesized and characterized using HNMR, CNMR, IR, and HRMS. With benzenesulfonohydrazide as the identification group, the probe demonstrated a fast fluorescence response from yellow-green to blue when the HC = N double bond was oxidized and broken into an aldehyde group by HClO. The probe showed high selectivity and sensitivity towards HClO with approximately 4.5-fold fluorescence enhancement and has been successfully applied in the molecular logic gate, determination of HClO in environmental water samples, and portable HClO detection.
合成了一种用于选择性检测HClO的新型菲并咪唑基荧光探针，并利用核磁共振氢谱（HNMR）、碳核磁共振谱（CNMR）、红外光谱（IR）和高分辨质谱（HRMS）对其进行了表征。该探针以苯磺酰肼为识别基团，当HC=N双键被HClO氧化并断裂形成醛基时，探针表现出从黄绿色到蓝色的快速荧光响应。该探针对HClO具有高选择性和高灵敏度，荧光增强约4.5倍，并已成功应用于分子逻辑门、环境水样中HClO的测定以及便携式HClO检测。
