Problems solved by technology

The currently commercialized electrochemiluminescent compounds are mainly terpyridine ruthenium compounds, but they have obvious disadvantages, such as: the luminous color is relatively single, the luminous quantum efficiency is low, and the luminous wavelength is difficult to adjust through the molecular structure.
These disadvantages limit the application of electrochemiluminescent systems

Abstract

The invention discloses an electrochemical luminescence compound and an application thereof. The electrochemical luminescent efficiency of the electrochemical luminescence compound is obviously superior to that of commonly-used electrochemical luminescence immune marker molecule tris-bipyridine ruthenium, and the electrochemical luminescence compound can be prepared into an electrochemical luminescence system which has good electrochemical luminescent efficiency in various luminescent modes; meanwhile, the electrochemical luminescence compound also has good electrochemical luminescence performance without a co-reaction compound; and moreover, the luminescent wavelength can be adjusted from blue light to red light by virtue of changes of a ligand structure, so that the molecules have important potential application values and huge market potential in electrochemical luminescence immunoassay.
