Abstract

A super lattice: The title system allows the spontaneous formation of self-assembled 2D and 3D highly ordered aggregates of standing nanorods on large superlattice domains (see picture). The hexagonal close packing of nanorods perpendicular to the substrate resembles smectic-B liquid-crystalline phases. Optical characterization of the aggregates demonstrates their anisotropic optical response.
