摘要：
A unique type of novel supramolecular hybrid hydrogel based on the co-assembly of the anionic polyoxometalate and the cationic ABA triblock copolymer via electrostatic interaction was reported to show jellyfish-like switchable chromic luminescence. The hydrogel undergoes reversible sol-gel transition in response to pH changes, and simultaneously exhibits an unprecedented luminescent chromism from weak green to strong white.
