Colloidal syntheses have advanced such that nanocrystals with size- and shape-control can be routinely achieved for many simple compositions. This extraordinary achievement provides eloquent nanocrystal samples for fundamental structure-property studies, revealing fascinating confinement effects that are being leveraged in a diversity of technologies. However, general syntheses for multimetalilc and multicomponent nanocrystals with defined structural features are far less developed. Yet, predictable pathways toward such nanostructures are essential to take advantage of the synergy and multifunctionality that arises from their compositional complexity. This presentation will outline predictable and generalizable syntheses for high-quality multimetallic nanostructures based on nanocrystal conversion pathways, including the thermal conversion of core@shell nanocrystals into high entropy alloy nanocrystals and the transformation of intermetallic nanocrystals into nanocrystal heterostructures with integrated atomic and nanoscale architectures through galvanic replacement.
