Modulation of dual electronic circuits of [26]hexaphyrins using internal aromatic straps.
Internal bridges: [26]Hexaphyrins with an aromatic strap in 5,20 position have two potentially cyclic conjugated networks, that is, [18]porphyrin and [26]hexaphyrin, and show a formal analogy with [18]annuleno[18]annulens. 1,3-Phenylene-, 2,5-thienylene-, and 2,5-pyrrylene-bridged [26]hexaphyrins have been synthesized and characterized.
