We have designed and synthesized a new tris-chelating polypyridine ligand (bpy3Ph) suitable to be used as a bridging ligand (BL) for constructing various supramol. photocatalysts. The ligand bpy3Ph has been used to prepare, according to a multi-step synthetic protocol, trinuclear supramol. photocatalysts containing different metal subunits. In particular, the compounds Ru2Re and RuRe2 have been prepared, containing different ratios of components based on Ru(dmb)32+-type and Re(dmb)(CO)3Cl-type units (dmb = 4,4′-dimethyl-2,2′-bipyridine), which can play the roles of photosensitizers and catalyst units for photocatalytic CO2 reduction, resp. The trinuclear model Ru3 and mononuclear and dinuclear Ru and Ru2 precursor metal complexes, containing free chelating sites, have also been synthesized using the same bridging ligand. The absence of negligible accumulation of the mono-reduced form of the photosensitizer indicates fast electron transfer to the catalyst unit(s) through the relatively large bridging ligand and is proposed to contribute to the outstanding photocatalytic properties of the new species, including their durability. The relevant photocatalytic behavior of the new systems indicates new avenues for the design of extended bridging ligands capable of efficiently and functionally integrating photosensitizers and catalysts towards the preparation of new, larger supramol. photocatalysts for selective CO2 reduction In the experimental materials used by the author, we found 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Category: pyridine-derivatives)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.Category: pyridine-derivatives Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.
