Clicking together: The Suzuki–Miyaura coupling of β,β′-diborylated porphyrin blocks and meso,meso′-dibrominated porphyrin blocks was used for the construction of directly meso–β doubly linked porphyrin rings including two tetraporphyrin rings, hexaporphyrin rings, and a bridged heptaporphyrin (see picture).
