Bridging the gap : A series of meso ‐to‐ meso pyrrole‐bridged cyclic porphyrins were prepared by a one‐pot Suzuki–Miyaura coupling reaction (see figure). The 1 H NMR spectra of these compounds revealed their highly symmetric structures in solution, and the solid‐state structures of nickel and zinc derivatives were determined by X‐ray crystal analysis. The UV/Vis absorption spectra of the cyclic arrays indicate the strong excitonic interactions among porphyrins.
