Abstract

We discuss the main features of the potential energy landscape that are associated with efficient ’structure-seeking’ systems for particles interacting via anisotropic{,} pairwise additive forces. The interparticle potentials employed here are intended for a coarse-grained description of mesoscopic building blocks{,} such as colloids or functionalised metal clusters. We show that the anisotropy of the building blocks and the orientation-dependent interaction strengths are the most important factors that govern self-assembly into particular target morphologies. By varying the model parameters{,} the self-assembling behaviour can be systematically tuned. Design principles are outlined for various structures{,} and we postulate a sufficient condition for building-blocks to self-assemble into helical strands.
