Novel mono- and dinuclear tricarbonylrhenium(I) complexes of formula [Re(Mebpy-CN)(CO)3Cl] (1), [Re(Mebpy-CN)(CO)3(CH3CN)](PF6) (2), and [(CH3CN)(CO)3Re(Mebpy-CN)Ru(NH3)5](PF6)3 (3), in which Mebpy-CN = 4-methyl-2,2′-bipyridine-4′-carbonitrile, were prepared and characterized by spectroscopic, photophysical, and computational techniques. The complete structure of complex 2 was determined by X-ray diffraction

We report in this work the synthesis and spectroscopic, electrochemical, spectroelectrochemical, and photophysical characterization of a novel series of ruthenium polypyridyl complexes with 4-methyl-2,2′-bipyridine-4′-carbonitrile (Mebpy-CN) as an auxiliary ligand of general formula [Ru(bpy)3–x(Mebpy-CN)x](PF6)2 (x = 1–3) (with bpy = 2,2′-bipyridine). A significant increase in the lifetime and quantum

electrochemical techniques. When introducing peripheral rutheniumammines to complex (1) using Mebpy-CN as a bridging ligand in complexes (2) to (4), the molar absorptivities increase in the visible region with increasing nuclearity of the complex. When oxidizing the Ru centers in the heteropolynuclear species, the corresponding three mixed-valent species are obtained, displaying IVCT (intervalence charge transfer)

nitrile-substituted bipyridines that can be anchored to semiconductor surfaces to be assembled in DSSCs, were synthesized and characterized by spectroscopic and electrochemical techniques. The crystalstructures of both species were determined by X-ray diffraction. Results from DFT and TD-DFT calculations were found to be consistent with the experimental data. Emission at room temperature was observed
合成了两种新型 Cu( I ) 四齿杂配配合物,包括可以锚定到半导体表面并组装在 DSSC 中的腈取代联吡啶,并通过光谱和电化学技术进行了表征。两种物质的晶体结构均通过 X 射线衍射测定。 DFT 和 TD-DFT 计算结果与实验数据一致。在固态下观察到两种配合物在室温下的发射,这使得它们成为发光二极管开发的有希望的替代品。我们首次报道了由 Cu( I ) 配合物通过取代联吡啶中存在的腈基锚定到 TiO 2表面形成的光伏转换器件的实验证据,并随后作为 DSSC 的敏化剂进行了测试,获得了光转换的效率值。电能转换类似于之前报道的具有锚定羧基的类似复合物的转换。
