Abstract
The preparation of colloidal molecules, i.e. clusters of colloids with a defined aggregation number and configuration, is of continued and significant interest in colloid chemistry and materials science, and numerous interactions have been utilized to drive their (self-)assembly. However, only very few reports are available on the assembly of colloidal molecules based on host-guest chemistry. In this paper, we investigate the assembly of like charged silica particles into well-defined, core-satellite ABn-type colloidal molecules in water mediated by host-guest interaction and geometric constraints. Exploiting the inherent dynamics of non-covalent attraction and making use of a soft polymer shell to enhance multivalent host-guest interactions, we successfully synthesized AB3, AB4 and AB6 colloidal molecules by selecting the appropriate size ratio of satellite to core particles.
