Selective iodide chemosensing through a redox-active Cu-corrole

An electron deficient Cu(iii)-corrole (B) has been identified as a highly selective colorimetric sensor for iodide. A one-electron redox couple between iodide and Cu(iii)-corrole serves as the basis for selectivity. The proposed mechanism has been supported by UV-vis and super(19)F NMR studies and f...

Zusammenfassung:An electron deficient Cu(iii)-corrole (B) has been identified as a highly selective colorimetric sensor for iodide. A one-electron redox couple between iodide and Cu(iii)-corrole serves as the basis for selectivity. The proposed mechanism has been supported by UV-vis and super(19)F NMR studies and further by unambiguous identification of Cu(ii) species through EPR.
