Electrogeneratedchemiluminescence (ECL) is a consequence of the electron-transfer reactions byspecies generated at electrodes, which provides the energy for the formation ofan excited state species that emits light upon relaxation to the ground state. ECLstudies of metal complexes have drawn intensive attention due to their highemission efficiencies, stable redox chemistry, and potential to harvestexcitons of both singlet and triplet spin states. Metal complex ECL also providesan efficient method to screen candidates for light-emitting diodes. Compared toRu(II) complexes, ECL of Pt(II) complexes is much less explored. In particular,the ECL of conducting metallopolymers has not been developed. We synthesized N^C^Nligands based on 1,3-bis-pyridine-2-yl-benzene and 1,3-bis-pyrazolyl-benzene,and their derivatives with polymerizable thiophene groups. The conductingmetallopolymers are prepared by electropolymerization of the Pt(II) monomers.The electrochemistry, photophysics and ECL of these complexes and correspondingmetallopolymers will be discussed.
