Durch Inversionssymmetrie erhöht sich die Lebensdauer des angeregten Zustands eines molekularen Rubins bei Raumtemperatur in flüssiger Lösung auf 4.5 ms, während die Photolumineszenzquantenausbeute bis zu 8.2 % beträgt. In ihrem Forschungsartikel auf S. 18243 zeigen K. Heinze et al., dass der Chrom(III)‐Komplex [Cr(tpe)2]3+ sich zudem für lichtinduzierte Energie‐ und Elektronenübertragungsprozesse...
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 [CrN6] chromophore [Cr(tpe)2]3+ with close to octahedral symmetry (tpe=1,1,1‐tris(pyrid‐2‐yl)ethane). [Cr(tpe)2]3+ exhibits...
