Selective detection of Hg(II) ions in solution by a series of novel free base bis-(nitrophenyl) corroles (1–4) with general formula A2B (where A = nitrophenyl, and B = N,N-dimethylaminophenyl, thienyl, naphthyl and tridecyloxyphenyl group) is described. Among the free base corroles, 4, with a tridecyloxy long chain moiety, has been found to exhibit the highest Hg(II) sensing ability. The detection is based on the fluorescence quenching of the corroles, arising from the combined effect of static (coordination) and dynamic (exciplex formation) factors.
介绍了一系列通式为 A2B(其中 A = 硝基苯基,B = N,N-二甲氨基苯基、噻吩基、萘基和十三烷氧基苯基)的新型游离碱双(硝基苯基)腐蚀剂(1-4)对溶液中 Hg(II) 离子的选择性检测。在这些游离碱腐蚀物中,发现具有十三烷氧基长链分子的 4 具有最高的 Hg(II)感应能力。检测是基于腐蚀剂的荧光淬灭,这是静态(配位)和动态(形成复合物)因素共同作用的结果。
