摘要: Abstract A series of novel metal complexes, [Cu2(dppm)2(OOCL)]2[NO3]2 (1), [Ag2(dppm)2(OOCL)2] (2) and [Au2(dppm)2(OOCL)2] (3) (dppm = bis(diphenylphosphino)methane, L = 2-cyano-3-(4-(diphenylamino) phenyl)acrylic acid) were prepared structurally characterized by X-ray crystallography. Their optical properties investigated absorption fluorescence spectra. The spectra the complexes showed red shifts relative to that L, which exhibited same tendency as In addition, ability 1–3 generate electrochemiluminescence (ECL) assessed in acetonitrile solutions, they a highly enhanced stable ECL emission compared free ligand (L). Especially, intensity 1 was approximately 30 times greater than L.
