Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

Bis(ferrocenyl) derivatives 3a, 3c and 3d containing secondary chelating substituents act as efficient voltammetric sensors of Mg2+ and Zn2+ ions in acetonitrile solution in concentrations as low as 10 mol%: a new redox peak appears in the cyclic voltammogram, positively shifted by 170-225 mV for 3a, 160-175 mV for 3c and 160-170 mV for 3d. Compounds 3b and 4 are selective for Zn2+ (215 mV shift) and Mg2+ (205 mV shift) ions, respectively, whilst 3d is also responsive to Ca2+ ions (165 mV shift) with no interference from a large excess of several other metal salts. The X-ray crystal structure of 3a is also reported.
