The present invention provides an improved redox couple for electrochemical and optoelectronic devices. The redox couple is based on a complex of a first row transition metal, said complex containing at least one mono-, bi-, or tridentate ligand comprising a substituted or unsubstituted ring or ring system comprising a five-membered N-containing heteroring and/or a six-membered ring comprising at least two heteroatoms, at least one of which being a nitrogen atom, said five- or six-membered heteroring, respectively, comprising at least one double bond. The invention also relates to electrolytes and to the devices containing the complex, and to the use of the complex as a redox couple.
本发明提供了一种改进的氧化还原偶对,用于电化学和光电子器件。该氧化还原偶对基于第一行过渡金属的配合物,所述配合物至少含有一个单、双或三齿配体,包括一个取代或未取代的环或环系统,其中包括一个五元N-含杂环和/或一个至少含有两个杂原子的六元环,其中至少一个是氮原子,所述的五元或六元杂环分别包括至少一个双键。该发明还涉及电解质、含有该配合物的器件,以及将该配合物用作氧化还原偶对的用途。
