【 摘 要 】

Herein we report a redox‐active metal‐organic framework (MOF) via post‐synthetic cation exchange with tris(2,2′‐biprydine) ruthenium(II) complex (Ru(bpy)32+). A porous anionic zinc‐adeninate framework (bMOF‐100) is spacious enough to easily entrap 2.43 of Ru(bpy)32+ cations within the mesopore. The encapsulation supported the framework structure preventing any distortion from a rapid solvent evaporation under SEM observation. Ru(bpy)32+@bMOF‐100 was then immobilized on the surface of glassy carbon electrode, and its electrocatalytic and electrochemiluminescent (ECL) properties were investigated in aqueous and organic solution. Especially, Ru(bpy)32+@bMOF‐100 showed the excellent electrochemical properties of Ru(bpy)32+, but gradual decomposition of the MOF structure was observed under electrochemical measurements because of the sluggish oxidation of adeninate ligand.
