A study was conducted to prepare micrometer-sized amorphous infinite coordination polymer (ICP) particles from organometallic ligands and metal ions for hydrogen storage. The study found a new group ICP particles based on metallo-salen connector groups and Zn2+ nodes. The gas sorption properties of the ICP materials also has been investigated. It was observed during the study the these novel materials show excellent H2 uptake properties and zero N2 adsorption properties. The study used homochiral acid-functionalized salen ligand (AFSL) and synthesized it with acid-functionalized salicylaldehyde and (1R,2R)-(-)-1,2-diaminocyclohexane. The study also found that the DMF/ether mixture can increase amorphous particle formation and pyridine/ether solvent mixture can increase the formation of a crystalline macrocycle.
