Chlorophyll f (Chl f )‐containing Photosystem II absorbing in the far red has transgressed the red limit of photosynthesis locked by chlorophyll a at 680 nm and drives water oxidation at 727 nm. A phthalocyanine chromophore with similar absorption properties as Chl f was stitched to a model of tyrosine Z /histidine, the pair of amino acids that enables electron relay between the Chl f and the Mn 4 Ca water oxidizing complex. In their Communication on page 12284, Annamaria Quaranta, Ángela Sastre‐Santos, Ally Aukauloo, and co‐workers report evidence that these chromophores can mirror the photoactivity of Chl f .
