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.
介绍了铁、钴、钌、锇和钒的新型过渡金属络合物。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媒介。在这种情况下,过渡金属络合物能从酶中高速接受电子或将电子传递给酶,同时还能与传感器快速交换电子。过渡金属配合物包括至少一种取代或未取代的双咪唑配体,还可包括第二种取代或未取代的双咪唑配体或取代或未取代的联吡啶或吡啶基咪唑配体。此外,还介绍了附着在聚合物骨架上的过渡金属配合物。
