Title:
PHOTOSENSITIZER FOR A PHOTOCATHODE
Document Type and Number:
WIPO Patent Application WO/2019/115012
Kind Code:
A8
Abstract:
An improved photosensitizer for a photocathode comprises an oligomeric or polymeric chromphore absorbing, as an ensemble, light at (a) wavelengths at or greater than 420 nm that includes at least 3 identical or different suitable monomeric chromophore units carrying at least two substituents each comprising at least one alkylene, alkenylene and/or alkynylene chain having a chain length of at least 3 carbon atoms, those substituents being terminated by thiol groups, wherein the oligomeric or polymeric chromphore has a disulfide bond between each of the chromophores. A photocathode comprising the photosensitzer is useful for the reduction of water-soluble chemicals in oxidized forms, including protons, with the aid of visible light in a system comprising the photocathode and a photoanode or any other anode or source of electrons. A method for reducing chemicals soluble in aqueous media in oxidized forms, including protons, in aqueous solutions by means of the photocathode is also disclosed.
