Atom-Anchoring Strategy with Metal–Organic Frameworks for Highly Efficient Solid-State Electrochemiluminescence

A chemical fixation strategy originating from single-atom-anchoring with metal–organic frameworks as a carrying matrix was proposed for solid-state electrochemiluminescence (ECL). Herein, UiO-67­(N) with the exposure of 2,2′-bipyridine (bpy) ligands could coordinate with Ru2+ to form a local structu...

Zusammenfassung:A chemical fixation strategy originating from single-atom-anchoring with metal–organic frameworks as a carrying matrix was proposed for solid-state electrochemiluminescence (ECL). Herein, UiO-67­(N) with the exposure of 2,2′-bipyridine (bpy) ligands could coordinate with Ru2+ to form a local structure of [Ru­(bpy)3]2+ (Ru-UiO). The influence of the steric effect induced with different Ru sources was discussed. The as-obtained Ru-UiO exhibits high ECL intensity and outstanding stability in the presence of a coreactant at low concentrations. The proposed synthesis strategy may hold great potential for the synthesis of solid-state ECL materials and their further utilization in ECL analysis.
