Chiral Inorganic Nanostructures from Achiral Platforms: A Universal Synthesis Route via Supramolecular Self-Assembly

Abstract: The chirality of nanostructured systems has gained growing attention in catalysis, biotechnology, and optoelectronics owing to their exotic enantio-/spin-selective interactions and intriguing chiroptical features. However, large-scale fabrication of chiral inorganic nanostructures still remains a challenge. Herein, we report a simple but generalized route for the synthesis of diverse chiral inorganic nanoparticles (NPs) such as Au, Ag, PdO, and TiO2 NPs using block copolymer (BCP) templates. The self-assembled… Show more

“…The creation, investigation, and application-driven use of chiral organic as well as inorganic nano-and microfilaments remain very active and attractive fields of research. 58,[193][194][195][196][197][198][199] While this review specifically focused on developing an understanding of what ultimately leads to chiral twisting and writhing in organic materials, their use as templates for inorganic nanomaterials or emitters aimed at a wide range of applications will continue to drive research in this expanding field.…”

“…Kim utilized linear polystyrene-block-poly(4-vinylpyridine) as templates with chiral additives, to synthesize chiral Au, Ag, and metal oxide nanoparticles through in situ growth within the corresponding micelles. 35 Notably, chiral plasmonic nanocrystals usually exhibit size-dependent properties, but the existing size controllability is not precise enough. Thus, the clarification of the size effect on optical activities and enantioselective recognition still remains challenging.…”

“…Soft templates (polymers, peptides, and DNA) as one of the popular bottom-up methodologies have displayed significant advantages of the mature polymerization techniques and diverse monomers, which allows for the hierarchical regulation on components and optical properties. Kim utilized linear polystyrene- block -poly­(4-vinylpyridine) as templates with chiral additives, to synthesize chiral Au, Ag, and metal oxide nanoparticles through in situ growth within the corresponding micelles . Notably, chiral plasmonic nanocrystals usually exhibit size-dependent properties, but the existing size controllability is not precise enough.…”

“…Compared with hard templates, , soft templates (DNA, peptides, and polymers) are sensitive to external conditions and thus display chiral tunability . Polymer-based templates such as homopolymers, block copolymers, , and unimolecular micelles , possess a wide range of sources, structures, and mature polymerization technology, which broaden the structural design and bring more possibilities for various purposes . Unimolecular micelles from multi-armed polymers are covalently bonded and structurally stable, while various morphologies (dendritic, spherical, cyclic) could be obtained .…”
