摘要
A chemo-sensor [Ru（bpy）2（bpy-DPF）]（PF6）2 （1） （bpy = 2,2＇-bipyridine, bpy-DPF = 2,2＇-bipyridyl-4,4＇- bis（N,N-di（2-picolyl））formylamide） for Cu2＋ using di（2-picolyl）amine （DPA） as the recognition group and a ruthe- nium（II） complex as the reporting group was synthesized and characterized successfully. It demonstrates a high se- lectivity and efficient signaling behavior only for Cu2＋ with obvious red-shifted MLCT （metal-to-ligand charge transfer transitions） absorptions and dramatic fluorescence quenching compared with Zn2＋ and other metal ions.
