The Amplified Electrochemiluminescence Response Signal Promoted from the Ir(III)-containing Polymer Complex

Abstract

A novel Ir(III)-containing polymer complex (P2) as an electrochemiluminescence (ECL) emitter was prepared by coordination reaction of the N-containing bidentate ligand (-CH=N-CH2-CH2-N=CH-) in the conjugated polymer P1 with [Ir2(2-ppy)4(µ-Cl)2] (M3). Despite rather low Ir(III) content in P2, it can emit greatly enhanced ECL signal compared with its polymer ligand P1 and the Ir(III) model complex using TPrA as co-reactant in CH3CN solution due to the effective intramolecular metal-ligand charge transfer (MLCT) from Ir(III)-complex centre to the polymer backbone.
