Octopus-porphyrins: their assembly and oxygen-binding in aqueous medium

Abstract
Amphiphilic tetraphenylporphyrins having four alkyl phosphocholine groups on each side of the ring plane (octopus-porphyrins) form fibrous aggregates in dilute aqueous solution; the vesicles, constituted by iron(II) derivative–1-dodecyl-2-methylimidazole (DMIm), have the ability to bind dioxygen reversibly in aqueous medium.
