Electrochemiluminescent polymer films with a suitable redox “turn-off” absorbance window for remote selective sensing of Hg2+
Abstract
An electrochemiluminescent sensing scheme is presented for remote detection of Hg2+ through an ITO-coated nanostructured optical fibre bundle. It is based on the electropolymerisation of CPDT-linked ruthenium phenanthroline complexes carrying azacrown ethers as the receptor units (CPDT =
