“Host in Host” Supramolecular Core–Shell Type Systems Based on Giant Ring?Shaped Polyoxometalates

چکیده

Herein, we show how the chaotropic effect arising from reduced molybdate ions in acidified aqueous solution is able to amplify drastically weak supramolecular interactions. Time-resolved Small Angle X-ray Scattering (SAXS) analysis suggests that molybdenum-blue oligomeric species form huge aggregates presence of ?-cyclodextrin (?-CD) which results fast formation nanoscopic {Mo154}-based host-guest species, while diffraction reveals ending-point scenario an unprecedented three-component well-ordered core–shell-like motif. A similar arrangement was found by using preformed hexarhenium chalcogenide-type cluster [Re6Te8(CN)6]4? as exogenous guest. This seminal work brings better understanding self-assembly processes general and gives new opportunities for practical applications design complex multicomponent materials via simplicity non-covalent chemistry.

Supramolecular polymers constructed by orthogonal self-assembly based on host-guest and metal-ligand interactions.

Supramolecular polymers constructed by orthogonal self-assembly based on host-guest and metal-ligand interactions are attracting increasing attention currently because of their interesting properties and potential applications. Host-guest interactions impart these polymers with good selectivity and convenient enviro-responsiveness, and metal-ligand interactions endow them with various coordinat...
