[Ru(bpy)3]2+ nanocomposites containing heteropolyacids: simple preparation and stable solid-state electrochemiluminescence detection application.
In order to solidify the electrochemiluminescence (ECL) luminophor tris(2,2'-bipyridyl) ruthenium(II) ([Ru(bpy)(3)](2+)) onto the electrode surfaces robustly, the negative charged heteropolyacids (HPAs) moieties were utilized to attract and bond cations [Ru(bpy)(3)](2+) via an adsorption method. The compositions and microstructures of the hybrid complexes were characterized by elemental analysis (EDS), spectroscopic techniques (UV-vis, FTIR) and field-emission scanning electron microscopy (FE-SEM). The electrochemical and ECL behaviors of the [Ru(bpy)(3)](2+)/[PW(12)O(40)](3-) hybrid complex contained in the solid film of the nanocomposites formed on the electrode surfaces were also studied. It was found that the corresponding solid membranes exhibited a diffusion-controlled voltammetric feature and excellent electrochemiluminescence behaviors. Hence potential prospects as new electrochemiluminescent materials for application in electroanalytical detection are envisioned.
