Monolayered octopus-porphyrin vesicle: microstructure and oxygen-binding in aqueous medium
Abstract
The amphiphilic tetraphenylporphin derivative having four dialkylglycerophosphoctoline groups on both sides of the ring plane (octopus-porphyrin) forms spherical monolayered vesicle membranas in water with diameters of ca. 100 nm; the vesicle constituted by octopus-porphyrinatoiron(II)/1-dodecyl-2-methyiimdazole (DMIm) can reversibly bind dioxygen at 25 °C.
