The invention relates to electronically neutral metal complexes as luminescent labels. The positive charge of the metal ion in the complex is neutralized by the negatively charged groups that are covalently linked to the nitrogen-containing diimine ligands, such as 2,2-bipyridine, 1,10-phenanthroline and their derivatives. The electronic neutrality reduces the impact of the metal complexes on the biological and/or biochemical activities of the labeled biomolecules, while the intensity of luminescent emission under electrochemical excitation is enhanced. These luminescent metal complex labels are useful in bioanalytic methodology development, with luminescence as the signal modality, such as electrochemiluminescence.
本发明涉及作为发光标签的电子中性金属配合物。络合物中金属离子的正电荷被与含氮二亚胺配体(如 2,2-联吡啶、1,10-菲罗啉及其衍生物)共价连接的带负电的基团中和。电子中性降低了金属复合物对标记生物大分子的生物和/或生化活性的影响,同时增强了电化学激发下的发光强度。这些发光金属复合物标签可用于开发以发光为信号模式(如电化学发光)的生物分析方法。
