Hybrid charged heterometallic Pt-Ir complexes: tailoring excited states by taking the best of both worlds.

The C≡C-linkage of Pt(PR(3))(2)(C≡CAr)(2) with (C^N)(2)Ir(N^N)(+) (C^N = 2-phenylpyridine; N^N = bipyridyl) leads to hetero-bi- and trimetallic species exhibiting photophysical properties reminiscent of both [Pt]- and [Ir]-containing moieties through the generation of a [Pt] → [Ir] charge transfer excited state.
