Acyclic and macrocyclic transition metal dithiocarbamate complexes containing imidazolium moieties for anion binding
摘要:
The synthesis of acyclic and macrocyclic transition metal dithiocarbamate complexes containing positively charged imidazolium moieties is reported. The assemblies have been characterised by a range of spectroscopic techniques and the ability of these compounds to bind various anions was also examined. UV-Vis spectroscopic binding studies revealed H2PO4- is complexed selectively in preference to F- and Cl- for the acyclic transition metal dithiocarbamate complexes containing the N-methylimidazolium moiety. Cyclic voltammetric studies demonstrated that the copper(II) dithiocarbamate imidazolium systems can electrochemically sense the binding of Cl- and H2PO4-. (C) 2004 Elsevier Ltd. All rights reserved.
