  本发明涉及汞离子检测技术领域，尤其是涉及一种检测汞离子的荧光探针及其制备、试剂盒和检测方法。本发明以常用的萘酰亚胺为荧光基团，以吡啶基团、哌嗪基团为结合位点，以PET（光诱导电子转移）和FRET（荧光共振能量转移）的概念为检测原理，构建得到了一个新型的配位诱导聚集的荧光发射探针。配位后汞离子切断了哌嗪和吡啶上氮原子的孤对电子向萘酰亚胺的转移（PET）过程，同时，喹啉和萘酰亚胺的距离被拉近，而前者的发射光谱和后者的吸收光谱重叠，导致在365nm紫外光源激发下，荧光共振能量转移（FRET）发生，喹啉的荧光淬灭，萘酰亚胺的荧光增强。该荧光探针对汞离子具有非常好的比率型荧光响应，且在水溶液和有机溶液中均有较好的溶解性。
