Tailored inter-particle coupling and substrate-supported plasmonic coupling effects are a prerequisite to generate electric and magnetic modes in colloidal optical metamaterials. Wrinkle-assisted self-assembly allows for the cost-effective construction of linear plasmonic arrays on macroscopic areas.[Soft Matter 2007, 3, 1530; Farad. Discuss. 2015, 181, 243] By multi-printing and selective transfer of assembled particle lines of defined morphology and periodicity, more complex structures are feasible.[Langmuir 2012, 28, 16745] Line spacing is determined by the template, whereas inter-particle spacing can be modified by a soft, polymeric spacer to tune the collective optical response. Thus, for the first time, we arrive at ensembles which show a clear signature of nanophotonic features in conventional UV/Vis/NIR spectroscopy homogenously over macroscopic areas, in accordance with electrodynamic simulations (GMMT, FDTD).[Nano Lett. 2014, 14, 6863] We present recent results in expansion of this assembly approach to anisotropic plasmonic nanocuboids and its perspectives toward metamaterial effects and concepts for light management.[Mater. Today 2014, 18, 185]
