The organic chemistry of ruthenium has been one of the most vigorously growing research areas over the past decades. Considerable effort has been extended towards the design and application of a broad series of ruthenium complexes, which culminated with the development by Ryoji Noyori (2001 Nobel Prize for Chemistry) of chiral ruthenium catalysts for stereoselective hydrogenation reactions [1], and the discovery by Robert H. Grubbs (2005 Nobel Prize for Chemistry) of well-defined ruthenium- benzylidene catalysts for olefin metathesis [2] [...].

The electrochemistry and spectroelectrochemistry of Ru(porphyrin)(NO)(phenoxide) complexes Ru(por)(NO)(OPh) (por = OEP, 1a; TAP, 2a; Ph = CH), Ru(por)(NO)(OAr) (por = OEP, 1b; TAP, 2b; OAr = -OCH-(2-NHC(O)CF)), Ru(por)(NO)(OAr) (por = OEP, 1c; TAP, 2c; OAr = OCH-(2,6-NHC(O)CF); OEP = octaethylporphyrinato dianion, TAP = tetraanisolylporphyrinato dianion) indicate that initial one-electron oxidation results in structure-dependent net reactivity at the phenoxide ligand. Oxidation of 1a generates 1a+, which undergoes a relatively slow rate-limiting second-order follow-up reaction. In contrast, 2a undergoes a diffusion-limited follow-up reaction after oxidation.

Azo dye was used to prepare a new series of complexes with chlorides of rhodium (Rh), ruthenium (Ru), and corona (Au). The prepared materials were subjected to infrared, ultraviolet-visible, and mass spectrometry, as well as thermogravimetric analysis, differential calorimetry, and elemental analysis. Conductivity, magnetic susceptibility, metal content, and chlorine content of the complexes were also measured.

The development of viable, stable, and highly efficient molecular water oxidation catalysts under acidic aqueous conditions (pH < 7) is challenging with Earth-abundant metals in the field of renewable energy due to their low stability and catalytic activity. The utilization of these catalysts is generally considered more cost-effective and sustainable relative to conventional catalysts relying on precious metals such as ruthenium and iridium, which exhibit outstanding activities. Herein, we discussed the effectiveness of transition metal complexes for electrocatalytic water oxidation under acidic conditions.

A supramolecular system, consisting of a tetrapyrenylporphyrinic core surrounded by arene-ruthenium prisms, has been assembled and characterized by means of electrochemical and photophysical techniques. The photophysical study shows that quantitative energy transfer from the peripheral pyrenyl units towards the central porphyrin core is operative in the tetrapyrenylporphyrinic system. Interestingly, encapsulation of the pyrenyl units into the ruthenium cages affects the photophysics of the central porphyrin component, since its emission quantum yield is reduced in the supramolecular array.
