Variation of two out of the six meso ‐aryl groups in Siamese‐twin porphyrin, an expanded porphyrin incorporating two pyrazole moieties, identified a set of substituents that result in optimized preparation of highly crystalline products. Electron‐donating and electron‐withdrawing aryl substituents have only negligible electronic and structural influences on the free‐base macrocycles (as measured by their UV/Vis absorption spectra and solid‐state structures, respectively) and their dicopper complexes (as measured by their cyclic voltammograms).
