Abstract
The strategy of hierarchical self-assembly of functional gels with anion-coordinated architecture junctions will open up a new avenue for the design and fabrication of a broad range of smart materials. In their Communication (DOI: 10.1002/anie.202201793), Dong Yang and co-workers report a series of C2-symmetric anion-binding ligands equipped with ortho-phenylene-bridged bis(urea) and amine or amide ends, which generated A2L3 triple helical architectures upon self-assembly with phosphate ions. Hierarchical intermolecular hydrogen bonds among the terminal amine/amide groups and urea moieties resulted in the formation of functional gels.
