Abstract
An oxygen separation membrane includes a porous material and a liquid complex contained in the porous material. The complex contains a metal salen complex or a derivative thereof and a first ionic liquid. The first ionic liquid is constituted by an anion having an amine structure and an imidazolium cation, an aliphatic quaternary phosphonium cation, or an ammonium cation that have alkyl chains, alkylene oxide chains, or alkyl ether chains with each 2 to 20 carbon atoms. The anion of the first ionic liquid is axially coordinated to a central metal ion of the metal salen complex or the derivative thereof.
