Abstract:
A new derivative of 2,6-bis(pyrazol-1-yl)pyridine (bpp) symmetrically substituted with 3,4-ethylenedioxy-thienyl (EDOT) substituent groups, and the corresponding ruthenium(II) complex was synthesized and characterized by NMR spectroscopy, elemental analysis, mass spectrometry, and single-crystal X-ray diffraction. A new linear conducting metallopolymer consisting of [Ru(bpp-(EDOT)(2) )(terpy)](2+) fragments was deposited directly on to electrode surfaces as a transparent, deep red film by electrochemical coupling of the pendant EDOT moieties. XPS analysis reveals that the film has the expected structure consisting of monomer repeats without degradation or loss of metal ions. Additionally, the absorption spectrum of the polymer film shows a broad absorption range from 310 to 700 nm.
