Fluorochromic Hydrogels: Dynamic Coordination of Eu–Iminodiacetate to Control Fluorochromic Response of Polymer Hydrogels to Multistimuli (Adv. Mater. 11/2018)

Europium-containing polymer hydrogels show fast self-healing and interesting switchable ON/OFF luminescence. In article number 1706526, Jie He and co-workers demonstrate the use of dynamic coordination of europium with iminodiacetates to construct hydrogel networks. This hydrogel presents controllable luminescence along with the sol–gel transition through the reversible formation and dissociation of metal–ligand complexes upon five different stimuli.
