The preparation of colloidal molecules (CMs), that is, 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 CMs based on host-guest chemistry. In this paper, we investigate the assembly of like-charged silica particles into well-defined, core-satellite AB n -type CMs in water, mediated by host-guest interactions and geometric constraints. Exploiting the inherent dynamics of noncovalent attraction and making use of a soft polymer shell to enhance multivalent host-guest interactions, we successfully synthesized AB 3 , AB 4 , and AB 6 CMs by selecting the appropriate size ratio of satellite to core particles. |
