Abstract:
Photoexcitation of a molecular pentad in the presence of Sc 3+ in de‐aerated CH 3 CN leads to a quinone dianion that is stable on the millisecond timescale. Light‐driven electron accumulation on the quinone unit is sensitized by two Ru(bpy) 3 2+ complexes in an intramolecular process, which relies on covalently attached triarylamine donors rather than on sacrificial reagents. Lewis acid–Lewis base interactions between Sc 3+ and quinone dianion are responsible for the exceptionally long lifetime of this photoproduct. Our study of photoinduced multi‐electron transfer is relevant in the greater context of solar energy conversion.
