【 摘 要 】

Using molecular dynamics (MD) computer simulations we show that a variety of complex, technologically relevant phases emerge from tuning aspects of nanoparticle architecture and interactions. In doing so, we demonstrate that nanoparticles can be thought of as building-blocks in larger scale assemblies over which we can tune nearly every aspect of the structure for specific applications such as photonics, photovoltaics, or catalysis. We highlight three specific case studies - polymer/nanoparticle composite building-block assemblies, star polymer microdroplets, and amino-acid coated nanoparticles with embedded dipoles that form rods of preferred chirality. In all cases predictions from simulations are used to either guide building-block assembly or to offer detailed insight into structures that were not previously understood. Additionally, we establish general, domain-agnostic mesophase behavior, as well as hypothesize synthesis and assembly strategies to target highly specific structures for any given application.
