  Fluorometric sensing of thiocyanate ions and competitive binding of anions in a family of CdII complexes of a phenol based ligand showing diverse structures

  摘要：

  A family of central phenoxido and terminal alcohol bound Cd-2 complexes have been synthesized and crystallographically characterized. Reaction condition and anion coordination (NO3-, NCS- and N-3(-)) dependent changeable structures have been identified in the four complexes 1-4 following varying coordination of the binucleating Schiff base ligand H(3)bemp (2,6-bis[(2-hydroxy ethylimino)-methyl]-4-methyl phenol) to cadmium(II) ions. These complexes have been characterized by X-ray crystallography, spectroscopic and analytical techniques. During the formation of 2 and 3, the phenoxido bridging unit of H(3)bemp is transformed to non-bridging modes of binding following the coordination of NO3- and NCS-, while changing one imine function on each ligand to the zwitterionic form, generated through a kind of acid-base reaction for metal ion coordination. The H(3)bemp molecule registers as a highly selective and sensitive fluorescent probe for Cd2+ in a PBS buffer (5 mM in pH = 7.1) at 25 degrees C. in the presence of Cd2+, the increase in fluorescence intensity is accounted for by the formation of [Cd-2(H(2)bemP)(2)](NO3)(2) (1) in solution. The fluorescence quantum yield of H3bemp is 0.201, and it increases more than 4-fold (0.851) in the presence of the cadmium ion. In presence of NCS-, complex 1 showed coordination induced fluorescence enhancement, whereas NO3- and N-3(-) anions quench the emission intensities significantly. (C) 2012 Elsevier Ltd.
