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.
据报道，一种基于阴离子多金属氧酸盐和阳离子ABA三嵌段共聚物通过静电相互作用共组装而成的新型超分子杂化水凝胶，呈现出类似水母的可切换变色发光特性。该水凝胶在pH值变化时会经历可逆的溶胶-凝胶转变，同时展现出从未有过的从弱绿色到强白色的发光变色现象。
