A G₄·K⁺ hydrogel made from 5′-hydrazinoguanosine and KCl reacts with α,β-unsaturated carbonyls of different electrophilicities (acrolein, methyl vinyl ketone and methyl acrylate) in water and the gas phase to form cyclic adducts. This aza-Michael addition/cyclization domino reaction by the 5′-hydrazino G₄·K⁺ hydrogel has promise for environmental remediation of toxic α,β-unsaturated carbonyls from water and the atmosphere.
