Imidazolium-based ionic liquids as efficient shape-regulating solvents for the synthesis of gold nanorods.

Herein we present an alternate synthetic strategy based onionic liquid solvents that alleviates the need for shape-regulating surfactants.Ionic liquids (ILs) have attracted interest as benignsolvent systems for the synthesis of nanomaterials as theycombine several attractive characteristics, for example inher-ent conductivity, stability over a broad range of electro-chemical potentials, and environmental benefits derivingfrom the low vapor pressure and straightforward separationprocedures.

1D periodic bimetallic superstructures by co-assembly of ternary block copolymer/nanoparticle blends

The formation of hierarchical 1D periodic bimetallic superstructures by co-assembly of ternary block copolymer/particle blend systems is reported. The results point to the relevance of entropy-driven morphology selection processes in enthalpic neutral block copolymer/particle blends that should render the presented approach applicable to a wide range of polymer/particle compositions.
