The amplified electrochemiluminescence response signal promoted by the Ir(III)-containing polymer complex

Abstract

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