The design of functional metallohydrogels is attractive but challenging. A rational approach is introduced for designing functional metallohydrogels using chiral ligands, a phenylalanine derivative with a pyridyl group ( l / d ‐PF). Intriguingly, the as‐prepared metallohydrogel exhibits excellent O 2 binding and activating properties. Insights into the O 2 binding pathway reveals the presence of a novel [( l + d )‐PF‐Cu 3+ ‐O 2 − ] species, which can efficiently reduce ferric cytochrome c with the reactive O 2 − by receiving an electron from reductant ascorbic acid. This study provides helpful instructions for developing new artificial systems with specific functions through the effective combination of chiral ligands with metal ions.
