Nanocrystallinity and direct cross-linkage as key-factors for the assembly of gold nanoparticle-superlattices†
Abstract
We report here how the crystallinity of AuNPs and the choice of binding sites of molecular cross-linkers control their aggregation. The combination of different binding moieties (N-oxides, ArF-I) and the reactivity of the particles' facets allow control over the organization and crystallinity of the AuNP assemblies.
