A method comprising (i) providing a metal organic framework formed by AlIII ions to which fumarate ions are coordinated to produce a porous framework structure,(ii) bringing a substance into contact with the metal organic framework such that the substance is uptaken by the porous metal organic frame

A method comprising (i) providing a metal organic framework formed by AlIII ions to which fumarate ions are coordinated to produce a porous framework structure,(ii) bringing a substance into contact with the metal organic framework such that the substance is uptaken by the porous metal organic framework to provide storage of or controlled release of, the substance.
