The oxidation of water to mol. oxygen is the key step to realize water splitting from both biol. and chem. perspective. In an effort to understand how water oxidation occurs on a mol. level, a large number of mol. catalysts have been synthesized to find an easy access to higher oxidation states as well as their capacity to make O-O bond. However, most of them function in a mixture of organic solvent and water and the O-O bond formation pathway is still a subject of intense debate. Herein, we design the first amphiphilic Ru-bda (H2bda=2,2′-bipyridine-6,6′-dicarboxylic acid) water oxidation catalysts (WOCs) of formula [RuII(bda)(4-OTEG-pyridine)2] (1, OTEG=OCH2CH2OCH2CH2OCH3) and [RuII(bda)(PySO3Na)2] (2, PySO3-=pyridine-3-sulfonate), which possess good solubility in water. Dynamic light scattering (DLS), scanning electron microscope (SEM), critical aggregation concentration (CAC) experiments and product anal. demonstrate that they enable to self-assemble in water and form the O-O bond through different routes even though they have the same bda2- backbone. This work illustrates for the first time that the O-O bond formation pathway can be regulated by the interaction of ancillary ligands at supramol. level. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Formula: C5H5NO3S
