Solid-state electrochemiluminescence of a novel iridium(III) complex

The solid-state ECL behavior of a water-insoluble bis-cyclometalated (pq)(2)Ir(N-phMA) complex is presented, in which pq is a 2-phenylquinoline anion and N-phMA is N-phenyl methacrylamide, a monoanionic bidentate ligand. The MWNTs/(pq)(2)Ir(N-phMA) film, MWNTs/Ru(bpy)(3)(2+) film and (pq)(2)Ir(N-phMA) directly modified glassy carbon electrode were fabricated; only the MWNTs/(pq)(2)Ir(N-phMA) film can produce steady ECL in the presence of tri-n-propylamine as a coreactant.
