摘要：

Metallo-supramolecular gels were prepared using a ligand macromolecule containing the tridentate 2,6-bis-(1,2,3-trizol-4-yl)pyridine (BTP) ligand unit synthesized via CuAAC "click'' chemistry in the main chain, together with transition metal ions and/or lanthanide ions. The gelation and gel properties, e. g. swelling, emission, rheological properties, thermo-and chemo-responsive properties, can be tuned by the careful selection of metal ions and their combinations, solvents, concentration, etc. Most interestingly, the gels exhibited repeatable autonomic healing ability. Moreover, the repeatable self-healing ability of the gels found practical application in the repairing of metal coatings.
