The cationic luminescence probe, tris(2,2'-bipyridyl)ruthenium(II) complex ([Ru(bpy)3]2+), was incorporated into laponite-modified glassy carbon electrode (GCE) via two strategies, namely, the adsorption and intercalation methods. These two incorporation methods resulted in different microenvironment for the immobilized [Ru(bpy)3]2+ within laponite as well as the different host-guest and guest-guest interactions. Herein, cyclic voltammetry and electrochemiluminescence (ECL) were innovatively performed to monitor the interactions. Tripropylamine (TPA) was used as coreactant in the electrochem. and ECL system.
