光催化水氧化是将太阳能转化为燃料的关键过程，可以通过使用分子过渡金属基催化剂来促进。通过制备含有两个[Ru（pdc）（pic）3]衍生单元的双核配合物（pdc = 2，6-吡啶二羧酸酯，pic = 4-甲基吡啶），证明了一种将催化单元共价连接到其它部分的新的直接方法.该复合物对水的化学和光化学氧化的活性进行了评价，并详细了解了催化剂和乙腈之间的相互作用，一种常见的共溶剂，用于增加水氧化催化剂的溶解度。通过电化学和光谱技术研究了溶剂诱导的转化，并提取了相关的定量参数。
Photocatalytic water oxidation represents a key process in conversion of solar energy into fuels and can be facilitated by the use of molecular transition metal-based catalysts. A novel straightforward approach for covalent linking of the catalytic units to other moieties is demonstrated by preparation of a dinuclear complex containing two [Ru(pdc)(pic)3]-derived units (pdc = 2,6-pyridinedicarboxylate, pic = 4-picoline). The activity of this complex towards chemical and photochemical oxidation of water was evaluated and a detailed insight is given into the interactions between the catalyst and acetonitrile, a common co-solvent employed to increase solubility of water oxidation catalysts. The solvent-induced transformations were studied by electrochemical and spectroscopic techniques and the relevant quantitative parameters were extracted.
