A Heteroleptic Bis(tridentate) Ruthenium(II) Complex of a Click‐Derived Abnormal Carbene Pincer Ligand with Potential for Photosensitzer Application

Long live the complex! A heteroleptic ruthenium(II) complex of a click-derived tridentate triazolylidene ligand (see graphic) and the parent terpyridine were prepared and investigated by experimental and computational methods. The new ligand enables excited-state lifetimes and room-temperature emission quantum yields that can compete with tris(bipyridine)ruthenium(II) complexes, but with the structural benefits of bis(terpyridine)ruthenium(II) complexes.
