摘要：A luminescent cyclic binuclear zinc-pamoate complex, [Zn-2(PAM)(2)(1,3-PDA)(2)] (1), has been synthesized by self-assembly of Zn(II) ions, 4,4'-methylenebis(3-hydroxy-2-naphthalenecarboxylic acid) (H(2)PAM) and 1,3-propanediamine (1,3-PDA) under hydrothermal condition and characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction analysis. In 1, two Zn2+ ions are bridged by two PAM ligands to form a 24-membered ring binuclear structure. The emission of 1 could be quenched efficiently and selectively by 2,4,6-trinitrophenol(TNP), indicating that 1 can serve as a selective chemosensor for the detection of TNP via a fluorescence quenching mechanism.
