A new paper entitled “Fluorochromic Hydrogels: Dynamic Coordination of Eu-Iminodiacetate to Control Fluorochromic Response of Polymer Hydrogels to Multistimuli” from He group is published in Advanced Materials as a cover story. Prof. 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. Read more>>>
