研究了双茂在水-有机溶剂两相体系中的光化学反应性，探讨了双茂的水裂解性质。采用电化学方法、紫外-可见光谱、气相色谱和核磁共振等方法研究了在厌氧条件下溶于1，2-二氯乙烷中的二茂金属诱导的水溶液质子光还原生成氢气，以及随后生成氢气过程中形成的二茂金属-金属二聚体对水的裂解.密度泛函理论计算用于验证反应途径。
The photochemical reactivity of osmocene in a biphasic water-organic solvent system has been investigated to probe its water splitting properties. The photoreduction of aqueous protons to hydrogen under anaerobic conditions induced by osmocene dissolved in 1,2-dichloroethane and the subsequent water splitting by the osmocenium metal-metal dimer formed during H-2 production were studied by electrochemical methods, UV-visible spectrometry, gas chromatography, and nuclear magnetic resonance spectroscopy. Density functional theory computations were used to validate the reaction pathways.
