  A NBD-based highly sensitive and selective colorimetric chemosensor for Ni2+ and Cu2+

  摘要：

  A new colorimetric chemosensor 1, containing the 7-nitrobenzo-2-oxo-1,3-diazolyl (NBD) moiety and the phenol one connected through Schiff-base linkage, has been synthesized. Sensor 1 showed remarkable color changes from pink to orange and pale brown, respectively, upon selective binding to Ni2+ and Cu2+ that can be identified by the naked-eye. The binding modes of sensor 1 to Ni2+ and Cu2+ were determined to be 1:1 stoichiometries using a Job plot and ESI-mass analysis. The sensor 1 showed high sensitivity toward Ni2+ and Cu2+ with the detection limits of 0.481.1M and 0.26 WI, respectively. The recognition properties of the sensor 1 toward Ni2+ and Cu2 were explained by using photophysical experiments and theoretical calculations. Practically, sensor 1 functioned as a visible test strip for Ni2+ and Cu2+. (C) 2017 Elsevier B.V. All rights reserved.

• Importance of <i>ortho</i> Proton Donors in Catalysis of Hydrazone Formation
  作者：Pete Crisalli、Eric T. Kool

  Anthranilic acids were recently reported as superior catalysts for hydrazone and oxime formation compared to aniline, the classic catalyst for these reactions. Here, alternative proton donors were examined with varied pK(a) in an effort to enhance activity at biological pH. The experiments show that 2-aminobenzenephosphonic acids are superior to anthranilic acids in catalyzing hydrazone formation with common aldehyde substrates.
