Protonation-Triggered Conformational Changes to Mobius Aromatic [32]Heptaphyrins(1.1.1.1.1.1.)

摘要

In recent years, the chemistry of expanded porphyrins has attracted considerable interest because of their unique properties such as extensive and flexible π conjugation, multimetal coordination, versatile oxidation states, anion binding, and large two-photon absorption cross section. A recent topic of interest is the ability of expanded porphyrins to form Mobius aromatic molecules.
