ABSTRACT
Integrating different types of supramolecular interactions opens the possibility to generate nanoparticle surfactants (NPSs) at the liquid-liquid interface that are responsive to multiple stimuli. Here we develop a covalently modified polyoxometalate/ß-cyclodextrin (POM/ß-CD) organic-inorganic hybrid, consisting of a negatively charged POM cluster with ß-CD host groups. The POM/ß-CD hybrid can be dispersed in water and interacts at a water/oil interface with ligands dissolved in an oil phase through electrostatic or host-guest interactions, thereby generating POM-surfactants (POMSs) having pH, redox, and guest-competitive responsiveness, respectively. By taking advantage of the jamming of POMSs at the interface, a reconfigurable all-liquid system could be produced that is responsive to orthogonal changes in the external environment.
