Novel transition metal complexes of iron, cobalt, ruthenium, osmium, and vanadium are described. The transition metal complexes can be used as redox mediators in enzyme based electrochemical sensors. In such instances, transition metal complexes accept electrons from, or transfer electrons to, enzymes at a high rate and also exchange electrons rapidly with the sensor. The transition metal complexes include at least one substituted or unsubstituted biimidazole ligand and may further include a second substituted or unsubstituted biimidazole ligand or a substituted or unsubstituted bipyridine or pyridylimidazole ligand. Transition metal complexes attached to polymeric backbones are also described.
本文介绍了铁、钴、钌、锇和钒的新型过渡金属配合物。这些过渡金属配合物可用作基于酶的电化学传感器中的氧化还原介质。在这种情况下,过渡金属配合物能够以高速率从酶中接收电子或将电子传递给酶,并且能够与传感器迅速交换电子。这些过渡金属配合物包括至少一个取代或未取代的双咪唑配体,并且可能还包括第二个取代或未取代的双咪唑配体、取代或未取代的联吡啶或吡啶咪唑配体。还介绍了连接到聚合物骨架上的过渡金属配合物。
