Abstract meso-Substituted trans-A 2 B 2-porphyrins bearing specific patterns of substituents are crucial building blocks in porphyrin-based biomimetic systems and molecular materials and can be used for the construction of well-defined porphyrin-based architectures. A new stepwise and rational synthesis of functionalized trans-A 2 B 2-porphyrins is reported in which for the first time donor–acceptor-substituted cyclopropane precursors (d–a ...
