AN ELECTROCHEMILUMINESCENT LABEL BASED ON MULTIMETALLIC ASSEMBLIES

摘要

Electrochemiluminescent label compounds containing multimetallic centers separated by bridging ligands are described. An example of a multimetallic electrochemiluminescent label suitable for use in electrochemiluminescence (ECL) methods [(bpy)2Ru]2(bphb)<4+>, demonstrates ECL efficiencies 2 to 3 times greater than those for Ru(bpy)3<2+> in acetonitrile and aqueous media. Such multimetallic ECL compounds may be especially useful in the design of new labels for bioanalytical applications, such as immunoassays and DNA probes.
