Spherical hybrid assemblies based on cationic surfactants and anionic porous polyoxometalate nanocapsules [{(Mo)Mo5O21(H2O)6}12{Mo2O4(SO4)}30]72 (Mo132 for short) are fabricated by the method combining an electrostatic encapsulation process and a polarity inducedself-assembly process. The spherical assemblies possess a size of several hundred nanometres and the incorporated Mo132 nanocapsules self-organize into a cubic phase stacking state in the assemblies. The ion-trapping properties of Mo132 are active in the assemblies, which enables the Mo132 to uptake and release Li+ ions. Furthermore, the speed of Mo132 uptaking and releasing Li+ ions in the assembliesis remarkably decreased compared with that of the naked Mo132, which shows that the microenvironment of the assemblieshas an efficient blockage effect on the interaction and recognition between Mo132 and Li+ ions, consequently delaying the ion-trapping process. This work not only presents a new route to assemble Mo132 nanocapsules but also demonstrates a new concept of using the microenvironment of supramolecular assembliesto adjust the ion-trapping properties of Mo132.
