Abstract
In this study, we report the successful incorporation of the photoactive bis(4′-(4-carboxyphenyl)-terpyridine)ruthenium(II) (Ru(cptpy)2) strut into a robust metal-organic framework (MOF), AUBM-4. The single crystal X-ray analysis revealed the formation of a new one-dimensional structure of Ru(cptpy)2 complexes linked together by Zr atoms that are eight coordinated with O atoms. The chemically stable MOF structure was employed as an efficient photocatalyst for carbon dioxide conversion to formate under visible light irradiation. To the best of our knowledge, the obtained conversion rate is among the highest reported in the literature for similar systems. Our strategy of using the Ru(cptpy)2 complex as a linker to construct the MOF catalyst appears to be very promising in artificial photosynthesis. © Copyright © 2019 American Chemical Society.
