Abstract:Lanthanide-containing
luminescent hydrogels have shown
potential
for sensing and imaging applications. Nonetheless, integrating lanthanide
ions or complexes into the polymer matrix often results in the poor
stability and mechanical strength of the hydrogels. This work presents
an innovative approach to fabricating luminescent hydrogels with three
dynamic cross-links: imine bond, boronate ester bond, and metal–ligand
coordination. Europium(III) (Eu3+) ions are incorporated
into a dual-cross-linked matrix compos… Show more
