Dynamic sol-gel interconversion by reversible cation binding and release in G-quartet-based supramolecular polymers.
The bis-guanine monomer G-G forms highly cross-linked, K+ stabilized, polymeric hydrogels that can be reversibly interconverted between gel and sol state via sequential binding and release of K+ by a cryptand undergoing protonation/deprotonation.
