  Rhodamine-derived Schiff base for the selective determination of mercuric ions in water media

  摘要：

  A new rhodamine-derived Schiff base (RS) was synthesized and its sensing property to metal ions was investigated by UV/vis and fluorescence spectroscopies. Addition of Hg2+ ions to the aqueous solution of RS gave a visual color change as well as significantly fluorescent enhancement, while other ions including Pb2+, Cd2+, Cr3+, Zn2+, Cu2+, Fe2+, Co3+, Ni2+, Ca2+, Mg2+, K+ and Na+ ions did not induce any distinct color/spectral changes, which constituted a Hg2+-selective fluorescent OFF-ON chemosensor. The Hg(2+)induced ring-opening of spirolactam of rhodamine in RS resulted in the dual chromo- and fluorogenic observation. (C) 2010 Elsevier B.V. All rights reserved.
