A novel fluorescent probe bearing triphenylamine, thiophene and thiosemicarbazide (TPA-TSC) was developed, and its distinct features were investigated. TPA-TSC demonstrated excellent selectivity towards Hg ions, with a limit of detection (0.14 nM) among the lowest reported to date. It also exhibited a turn-off response by forming stable complex for a brief period (<30 s). Job plot analysis and high-resolution mass spectrometry (HRMS) revealed that TPA-TSC bound to Hg with a 2:1 stoichiometry in an aqueous environment, remarkably the probe successfully detected Hg ions in seabass, swordfish and different samples of water. In all, TPA-TSC offers a promising method for accurately determining the quality of seafood and water samples polluted with Hg.
开发了一种新型的基于三苯胺、噻吩和硫代半卡巴腙（TPA-TSC）的荧光探针，并对其独特性能进行了研究。TPA-TSC 对 Hg 离子具有优异的选择性，检测限（0.14 nM）是迄今为止报道的最低值之一。它还通过形成稳定的配合物在短时间内（<30 s）产生关闭响应。Job 图分析和高分辨率质谱（HRMS）表明，在水溶液中，TPA-TSC 与 Hg 以 2:1 的化学计量比结合，该探针成功地检测到了海鲈、箭鱼和不同水样中的 Hg 离子。总之，TPA-TSC 为准确测定受 Hg 污染的海鲜和水样的质量提供了一种有前途的方法。
