title: Unexpected evolution of optical properties in Ir-Pt complexes upon repeat unit increase: towards an understanding of the photophysical behaviour of organometallic polymers.
abstract: The photophysical properties of [Ir]-[Pt]-[Ir]-[Pt]-[Ir] ([Ir] = [Ir(ppy)(2)(bpy*)](+) ([Pt] = trans-Pt(PBu(3))(2)(C≡C)(2); ppyH = 2-phenylpyridine); bpy* = bipyridyl;) reveal an unprecedented triplet energy transfer from the terminal iridiums to the central Ir subunit.
