Dioxygen binding of water-soluble iron(II) porphyrins in phosphate buffer at room temperature.
Two water-soluble tris(2-aminoethylamine) (tren) capped iron porphyrins were synthesized. The stability of their dioxygen adducts was studied in phosphate buffer, leading to half-life times around 7 min for the oxygenated species.
