Trans ‐ dichlorobis(tri‐n‐butylphosphine)platinum(II) reacts with bis(2‐ phenylpyridinato)‐(5,5′‐diethynyl‐2,2′‐bipyridine)iridium(III) hexafluorophosphate to form the luminescent conjugated polymer poly[trans‐[(5,5′‐ethynyl‐2,2′‐bipyridine)bis(2‐ phenylpyridinato)‐iridium(III)]bis(tri‐n‐butylphosphine)platinum(II)] hexafluorophosphate ([Pt]‐[Ir])n. Gel permeation chromatography indicates a degree of polymerization of 9 inferring the presence of an oligomer. Comparison of the absorption and emission band positions and their temperature dependence, emission quantum yields, and lifetimes with those for models containing only the [Pt] or the [Ir] units indicates hybrid excited states including features from both chromophores.
