Abstract: Methods of contacting a fluid comprising a light hydrocarbon with a metal-organic framework adsorbent having bis(pyrazolyl) ethanediimine ligands and internal pores; adsorbing the fluid in at least a portion of the internal pores of the metal-organic framework thereby creating an adsorbed fluid; storing the adsorbed fluid in the internal pores of the metal-organic framework; and releasing the adsorbed fluid from the internal pores of the metal-organic framework, wherein the metal-organic framework adsorbent undertakes a reversible phase transition upon adsorbing the fluid. Systems of a metal-organic framework having bis(pyrazolyl) ethanediimine ligands and internal pores, wherein the metal-organic framework undertakes a reversible phase transition upon adsorption and desorption of a light hydrocarbon fluid; wherein the fluid is stored in the internal pores of the metal-organic framework.
