The most popular building blocks in the construction of porphyrin‐based architectures are nickel porphyrins. Denickelation under highly acidic conditions has been indispensable in photophysical studies so far. In the Communication by H. Yorimitsu, A. Osuka et al. on p. 9123 ff. denickelation of nickel porphyrins by a Grignard reagent via magnesium porphyrins is disclosed, a process that provides fluorescent magnesium or free‐base porphyrins under non‐acidic conditions.
