We present results of molecular simulations that predict the phases formed by the selfassembly of model nanospheres functionalized with a single polymer “tether”. Microphase
separation of the immiscible tethers and nanospheres induces the formation of the double gyroid, perforated lamella and crystalline bilayer phases. Confinement effects promote the formation of
icosahedral arrangements of nanoparticles that help to stabilize the gyroid and perforated lamella phases. We also present a new metric for determining the local arrangement of particles in liquid
and solid configurations. Preprint, link to published version can be found below.
