Using a flexible and porous one-dimensional (1D) coordination polymer as an adsorbent the research team of Prof. Jing Li at Rutgers University ( has succeeded in complete separation of the three C6 cyclic hydrocarbons based on an ideal molecular sieving mechanism. The compound undergoes fully reversible structural transformation associated with removal/re-coordination of water molecules and between activated and hydrocarbon-loaded forms. It exhibits distinct temperature- and adsorbate-dependent adsorption behavior which facilitates the complete discrimination of benzene, cyclohexene and cyclohexane from their binary and ternary mixtures, achieving record-high uptake ratios for C6H6/C6H12 and C6H10/C6H12 in vapor phase and highest binary and ternary selectivities in liquid phase.
