Macrocyclic rings are an exciting functional group that enables synergetic host-guest capture and entrapment of substrates wthin its ring cavity. Our work explores the synthesis and infusion of these rings into hydrogel network using gamma radiation and chemical methods, for application in selective capture of metal ions. Selectivity is critical in both removal and/or recovery of target pollutant metal excisting in high shielded/competitive environment, such as radiocesium contamination on sea water. Using various spectroscopy tecnhiques, we also explore both intrinsic and extrinsic properties of these macrocyclic hydrogel types.
