“…The templating role of XB interactions was verified by studying the analogous assembly of either AuNPs with PEB (containing only one halogen-bond acceptor group) or perfluoro-functionalized AuNPs with BPEB: in both cases no significant clustering of AuNPs was observed by either UV−vis spectroscopy or TEM experiments. 246 In an extension of this strategy, AuNPs functionalized with XB donor ligands were self-assembled on surfaces coated with XB acceptors. 247 By comparison with their perfluoro analogue, van der Boom and co-workers have shown the attachment of AuNPs functionalized with (E)-4-(2,3,5,6-tetrafluoro-4-iodostyryl)pyridine-1-oxide onto planar functionalized surfaces is mediated by XB interactions (Figure 59).…”

The immobilization of metal nanoparticles (NPs) with molecular control over their organization is challenging. Herein, we report the formation of molecularly cross-linked AuNP assemblies using a layer-by-layer approach. We observed four types of assemblies: 1) small aggregates of individual AuNPs, 2) large aggregates of individual AuNPs, 3) networks of fused AuNPs, and 4) gold islands. Interestingly, these assemblies with the different cross-linkers and capping layers represent different stages in the complete fusion of AuNPs to afford islands of continuous gold. We demonstrate that the stability toward fusion of the nanoparticles of the on-surface structures can be controlled by the reactivity of the cross-linkers and the hydrophilicity/hydrophobicity of the nanoparticles.

“…Currently, to the best of our knowledge, there is only a limited amount of work that has focused on strategies and tactics for the synthesis of synthons on NPs. 7,8 Synthons are particularly useful for controlling molecular self-assembly due to the reversibility, specificity, directionality, and cooperative strength of the class of the interactions. Attempts have been made to apply NP synthons to the detection of melamine as food contaminant in raw milk in China, a situation that puts thousands of children at risk.…”

This article investigates recent research on a series of photoluminescent nanoparticles (NPs) and supramolecular chemistry at their surface. This in turn prompts the concept of quantum dots supramolecular synthons (QDSS) and foresees the inevitable path towards biomimetics and bioinspired technology. We highlight the methodology how to create QDSS by functional assembly of photoluminescent semiconductors and the surface binding of supramolecular ligands.Résumé : Le présent article fait l'examen de la recherche récente sur un ensemble de nanoparticules photoluminescentes et sur la chimie supramoléculaire qui a lieu à leur surface. Cette recherche nous amène à aborder le concept de boîtes quantiques de synthons supramoléculaires et laisse présager que son évolution vers la biomimétique et la technologie inspirée de la nature est inéluctable. Nous mettons en évidence la méthodologie permettant de créer des boîtes quantiques de synthons supramolécu-laires par assemblage de semi-conducteurs photoluminescents, ainsi que les propriétés de liaison en surface des ligands supramoléculaires. [Traduit par la Rédaction]Mots-clés : synthon supramoléculaire, boîte quantique, nanoparticule, liaison hydrogène.
