π-conjugated polymers are arguably one of the most exciting classes of materials and have attracted substantial attention due to their unique optical and electronic properties. The introduction of transition metals into conjugated polymers tunes the optoelectronic properties of these metallopolymers, which may improve their performance in device applications. Graphene and reduced graphene oxide (RGO) derivatives are interesting materials with a unique structure and outstanding properties. The present work reports an investigation of three hybrid RGO and π-conjugated oligomers that contain ruthenium polypyridyl chromophores serving as models to provide molecular-level insight for the corresponding transition-metal-containing conjugated polymers.

π共轭聚合物可以说是最令人兴奋的材料类别之一，因其独特的光学和电子特性而备受关注。将过渡金属引入共轭聚合物可调节这些金属聚合物的光电特性，这可能会提高它们在器件应用中的性能。石墨烯和还原氧化石墨烯（RGO）衍生物是具有独特结构和出色性能的有趣材料。本工作报道了对三种含有钌多吡啶发色团的RGO与π共轭低聚物的杂化物的研究，以此作为模型，为相应的含过渡金属共轭聚合物提供分子层面的见解。
