Tunable assembly of truncated nanocubes by evaporation-driven poor-solvent enrichment

Abstract

Versatile methods that can predictably assemble nanocrystals into large, well-ordered superlattices are rare. Here, the authors develop such a method–evaporation-driven poor-solvent enrichment–and rigorously determine the effect of various experimental parameters on the size, morphology, and mesoscopic order of the superlattices, giving the approach high predictive power.
