摘要：luminescent two-dimensional zinc-pamoate coordination polymer, [Zn(PAM)(en)] (1) (PAM = 4,4'-methylenebis(3-hydroxy-2-naphthalenecarboxylate), en = 1,2-ethanediamine) has been synthesized under hydrothermal conditions. The strong emission of 1 was quenched efficiently by adding trace amounts of 2,4,6-trinitrophenol (TNP), even in the presence of other interfering analytes such as 4-nitrophenol, 2,6-dinitrotoluene, 2,4-dinitrotoluene, nitrobenzene, 1,3-dinitrobenzene, hydroquinone, dimethylbenzene and bromobenzene, which exhibited superior selectivity of 1 for the detection of TNP via a fluorescence quenching mechanism. Similarly, 1 also exhibited unique selectivity and sensitivity toward Cu2+ compared to other metal cations such as Zn2+, Mn2+, Mg2+, K+, Na+, Ni2+, Co2+ and Ca2+. This reveals compound 1 can be used as a dual luminescence sensor for the detection of TNP and Cu2+ alternatively. (C) 2015 Elsevier B.V. All rights reserved.
