Substituted 2,4-Di(pyridin-2-yl)pyrimidine-Based Ruthenium Photosensitizers for Hydrogen Photoevolution under Red Light

The photocatalytic reduction of water to form hydrogen gas (H-2) is a promising approach to collect, convert, and store solar energy. Typically, ruthenium tris(bipyridine) and its many derivatives are used as photosensitizers (PSs) in a variety of photocatalytic conditions. The bis(terpyridine) analogues, however, have only recently gained attention for this application because of their poor photophysical properties. Yet, by the introduction of electron-donating or -withdrawing groups on the terpyridine ligands, the photophysical and electrochemical properties can be considerably improved. In this study, we report a series of nonsymmetric 2,6-di(pyridin-2-yl)pyrimidine ligands with peripheral pyridine substituents in different positions and their corresponding ruthenium(II) complexes. The presence of the pyrimidine ring stabilizes the lowest unoccupied molecular orbital, leading to a red-shifted emission and prolonged excited-state lifetimes as well as higher luminescence quantum yields compared to analogous terpyridine complexes. Furthermore, all complexes are easier to reduce than the previously reported bis(terpyridine) complexes used as PSs. Interestingly, the pyridine substituent in the 4-pyrimidine position has a greater impact on both the photophysical and electrochemical properties. This correlation between the substitution pattern and properties of the complexes is further investigated by using time-dependent density functional theory. In hydrogen evolution experiments under blue- and red-light irradiation, all investigated complexes exhibit much higher activity compared to the previously reported ruthenium(II) bis(terpyridine) complexes, but none of the complexes are as stable as the literature compounds, presumably because of an additional decomposition pathway of the reduced PS competing with electron transfer from the reduced PS to the catalyst.

Synthesis, Crystal Structure, and DFT Study of a New Compound 6-(2-Fluorophenyl)-N-(p-Tolyl)Imidazo[1,2-A]Pyridine-2-Carboxamide

6-(2-Fluorophenyl)-N-(p-tolyl)imidazo[1,2-a]pyridine-2-carboxamide is an organic intermediate having both functions of azabicyclo and amide groups. In this paper, the title compound is obtained by the ring closure reaction, the Suzuki reaction, the hydrolysis and amidation reactions. The structure of the compound is confirmed by FT-IR, H-l NMR, C-13 NMR spectroscopy, and MS. At the same time, a single crystal of the title compound is measured by X-ray diffraction and subjected to crystallographic and conformational analyses. The molecular structure is further calculated using density functional theory (DFT) and compared with the X-ray diffraction value. The results of the conformation analysis indicate that the molecular structure optimized by DFT is consistent with the crystal structure determined by single crystal X-ray diffraction. In addition, the molecular electrostatic potential and frontier molecular orbitals of the title compound are further investigated using DFT, revealing some physicochemical properties of the compound.
