A series of dinuclear ruthenium alkynyl and vinyl complexes bridged by carbazole, dibenzofuran, dibenzothiophene, and fluorenone have been prepared, and some representative molecular structures have been determined. The electrochemical and spectroscopic properties of the compounds were explored by cyclic voltammetry (CV), square-wave voltammetry (SWV), and in situ infrared and UV/Vis/near-IR spectroelectrochemical
制备了一系列由咔唑、二苯并呋喃、二苯并噻吩和芴酮桥接的双核钌炔基和乙烯基配合物,并确定了一些具有代表性的分子结构。通过循环伏安法 (CV)、方波伏安法 (SWV) 以及原位红外和紫外/可见/近红外光谱电化学方法研究了化合物的电化学和光谱性质。电化学结果表明配体上的电子密度越大,桥基氧化产物越稳定,电化学分裂越大。紫外/可见/近红外光谱电化学研究表明,桥接配体对氧化过程有很大贡献,甚至占主导地位。此外,
