We have designed and prepared a series of rhenium complexes with 4,4′-bipyridyl as an electron-accepting unit. Electrochemical studies revealed that oxidation and reduction of these complexes occurred on the rhenium center and the 4,4′-bipyridyl skeleton, respectively. The redox potentials of the rhenium complexes are controllable by tuning the substituents on the 4,4′-bipyridyl skeleton and the coordinating groups to the rhenium center. We have also examined the reactivity of the rhenium complexes in electrochemical and photochemical CO₂ reduction.

以4,4'-联吡啶为电子接受单元的可调节配体及其R配合物的设计与合成

我们设计并制备了一系列以4,4'-联吡啶为电子接受单元的rh配合物。电化学研究表明，这些配合物的氧化和还原分别发生在the中心和4,4'-联吡啶基骨架上。tuning络合物的氧化还原电势可通过调节4,4'-联吡啶基骨架上的取代基和to中心的配位基来控制。我们还检查了electrochemical配合物在电化学和光化学CO ₂还原中的反应性。
