of mononuclear cyclometalatedrutheniumcomplexes with 1,2,4,5-tetrakis(N-methylbenzimidazolyl)benzene have been prepared, where two N-methylbenzimidazoles bind to the metal center and others remain intact. Electronic properties of these complexes were investigated by electrochemical and spectroscopic studies and DFT/TDDFT computations. The RuII/III redox potentials of theses complexes can be modulated
已制备了一系列与1,2,4,5-四(N-甲基苯并咪唑基)苯的单核环金属化钌配合物,其中两个N-甲基苯并咪唑与金属中心结合,其余则保持完整。通过电化学和光谱学研究以及DFT / TDDFT计算研究了这些配合物的电子性质。这些配合物的Ru II / III氧化还原电势可通过将各种电子性质的取代基连接到非环化金属配体上来调节。与没有两个独立的N-甲基苯并咪唑基单元的那些配合物相比,这些配合物由于三色团效应而显示出增强的可见光吸收。
