Near infrared light-driven water oxidation in a molecule-based artificial photosynthetic device using an upconversion nano-photosensitizerElectronic supplementary information (ESI) available: Experimental section and additional data. See DOI: 10.1039/c5cc05102a

We provide the first demonstration of a near infrared light driven water oxidation reaction in a molecule-based artificial photosynthetic device using an upconversion nano-photosensitizer. One very attractive advantage of this system is that using NIR light irradiation does not cause significant photodamage, a serious problem in molecular based artificial photosynthesis under visible light irradiation. A NIR light driven nano-photosensitizer is reported as a novel concept in an artificial photosynthetic system that integrates upconversion nanoparticles with Pt( ii )-porphyrin.
