Supramolecular hydrogels for environmental remediation: G4-quartet gels that selectively absorb anionic dyes from water†
Abstract
Binary mixtures of guanosine (G 1) and 8-aminoguanosine (8AmG 2) form stable, transparent supramolecular hydrogels with stoichiometric concentrations of either K+ or Ba2+ salts. These hydrogels selectively bind anionic dyes.
