The one‐electron oxidation of compounds 1 H– 3 H occurs by a proton‐coupled electron‐transfer mechanism to produce a phenoxyl radical hydrogen‐bonded to an imidazolium carbon atom. Thus, these compounds serve as analogues for tyrosyl D . in photosystem II. This insight was obtained from a combination of W‐band EPR spectroscopy and DFT calculations.
