ResumoAbstract Expansion of the porphyrin π-system by peripheral substitution lowers the oxidation potential of the macrocycle and increases the photocurrent quantum yield obtained when the porphyrin is used as sensitizer in a photocell. Tetrabenzporphyrins fall among the most efficient porphyrin sensitizers studied so far with photocurrent quantum yields greater than 10% in the Al/Porphyrin/0.1 mol dm−3 K3[Fe(CN)6] and 0.1 mol dm−3 K4[Fe(CN)6]/Pt cell.
