Copper(I)-based dyes represent electronically tunable charge transfer and separation systems. Herein, we report a Cu(I)-bisdiimine donor-chromophore-acceptor dye with an absorbance in the visible part of the solar spectrum composed of a phenothiazine electron donor, and dipyrido[3,2-a:2',3'-c]phenazine electron acceptor. This complex is incorporated onto a zinc oxide nanowire semiconductor surface effectively forming a photoanode that is characterized spectroscopically and electrochemically. We investigate the photo-oxidation of hydroquinone, and the photosensitization of 2,2,6,6-tetramethylpiperidine-1-oxyl and N-hydroxyphthalimide for the oxidation of furfuryl alcohol to furfuraldehyde, resulting in near quantitative conversions, with poor selectivity to the alcohol.ChemSusChemMolecular Copper(I)-Sensitized Photoanodes for Alcohol Oxidation under Ambient Conditions.PMC11660751RGPIN-2018-04391Kamal SRicardo-Noordberg JFMajewski MBfalseMolecular Copper(I)-Sensitized Photoanodes for Alcohol Oxidation under Ambient Conditions.Dye-sensitized photoelectrochemical cells can enable the production of molecules currently accessible through energetically demanding syntheses.
