A new special pair model comprising meso-di-p-anisylaminoporphyrin: enhancement of visible-light absorptivities and quantification of electronic communication in mixed-valent cation radical.
Slipped cofacial porphyrin dimer 1(2) with di-p-anisylamino groups on the meso-positions shows characteristic photo- and electroproperties making it suitable as a photosynthetic special pair model: more intense and red-shifted absorptivities in the visible region, and electronic communication between the two porphyrins in mixed-valent cation radical 1(2)(+), which is quantified with an IVCT band analysis.
