4,4′-Substituted biphenyl coronands. Preparation of a new selective fluorescent sensor for mercury salts
摘要:
Six new 4,4'-substituted biphenyl coronands have been prepared. The ligands containing dimethylamino groups in the biphenyl moiety have been used in transition metal cations' complexation and one of them (3) has demonstrated to be a selective fluorescent sensor for mercury. Stoichiometries of the formed complexes and complexation constants have been determined by titration experiments. In addition, the extractant ability of some ligands has also been studied. Finally, the electrochemical properties of some of these ligands are also described. (c) 2006 Elsevier Ltd. All rights reserved.
