room temperature ionic liquids based on quaternaryphosphonium cations together with a dicyanamide anion are presented in this report. The most dicyanamide-based phosphonium ionic liquids prepared were hydrophilic, except ionic liquids containing a long alkyl chain in the phosohonium cation. It was found that asymmetric phosphonium cations gave low-melting salts in combination with a dicyanamide anion

A liquid having oxygen absorbing ability, comprising a cobalt-salen complex or a derivative thereof and an ionic liquid formed from an anion having an amine structure and a cation of an aliphatic quaternary phosphonium or ammonium having alkyl chains with each 2-20 carbon atoms, wherein the anion of the ionic liquid is coordinated to a cobalt ion of the cobalt-salen complex or a derivative thereof.
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.
