- Abstract
- <jats:title>Abstract</jats:title><jats:p>Photoactive metal complexes employing Earth‐abundant metal ions are a key to sustainable photophysical and photochemical applications. We exploit the effects of an inversion center and ligand non‐innocence to tune the luminescence and photochemistry of the excited state of the [CrN<jats:sub>6</jats:sub>] chromophore [Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup> with close to octahedral symmetry (tpe=1,1,1‐tris(pyrid‐2‐yl)ethane). [Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup> exhibits the longest luminescence lifetime (<jats:italic>τ</jats:italic>=4500 μs) reported up to date for a molecular polypyridyl chromium(III) complex together with a very high luminescence quantum yield of <jats:italic>Φ</jats:italic>=8.2 % at room temperature in fluid solution. Furthermore, the tpe ligands in [Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup> are redox non‐innocent, leading to reversible reductive chemistry. The excited state redox potential and lifetime of [Cr(tpe)<jats:sub>2</jats:sub>]<jats:sup>3+</jats:sup> surpass those of the classical photosensitizer [Ru(bpy)<jats:sub>3</jats:sub>]<jats:sup>2+</jats:sup> (bpy=2,2′‐bipyridine) enabling energy transfer (to oxygen) and photoredox processes (with azulene and tri(<jats:italic>n</jats:italic>‐butyl)amine).</jats:p>
