Abstract

[Ni(cod)₂]-mediated intramolecular reductive coupling of β–β′ linked meso,meso′-dibromosubporphyrin dimer gave the anti-isomer of meso–meso′, β–β′ doubly linked subporphyrin dimer as the first example of a fused subporphyrin dimer. The fused dimer 3_antidisplays an wavelike coplanar structure, a perturbed and red-shifted absorption spectrum, reversible redox behaviors with a decreased electrochemical HOMO–LUMO band gap, and a short S₁-state lifetime owing to the delocalized π-electronic network.
