| Abstract Scope |
Early observation of strong circular dichroism for individual nanoparticles (NPs) and their assemblies have developed into a rapidly expanding field of chiral inorganic nanostructures. The chiral inorganic nanostructures encompass sophisticated constructs from metals, semiconductors, ceramics, and nanocarbons with multiple chiral geometries with characteristic scales from Ångströms to microns. Many of them are formed spontaneously from polydispersed building blocks, which enables their structural and functional engineering over a broad range geometries and optical properties. This talk will address (1) the mechanisms of chirality transfer in inorganic materials, (2) the origin of the uniquely high values of optical anisotropy, (3) the fundamental challenges of multiscale chirality observed in nanostructures, and (4) physicochemical differences and similarities with chiral supramolecular, liquid crystal, and biological systems. Technological potential of chiral NPs assemblies is expected for real-time modulation of the polarization of light and enantioselective catalysis. The first realization of CD spectroscopy in terahertz spectral window will be demonstrated. |
