Summary: Chiral hybrid organic-inorganic metal halides (HOMHs) with intrinsic noncentrosymmetry have great potential in various applications. This study successfully constructed a series of chiral HOMHs using an induction approach, resulting in products with superior optical properties. The use of this induction approach could facilitate the construction of chiral HOMH libraries from achiral precursors.

Summary: The acquisition of strong chiroptical activity has revolutionized the field of plasmonics, enabling new light-matter interactions. Self-assembly of achiral nanoparticles into optically active materials simplifies engineering of chiral geometries and allows for control of structure-optical activity relationships in nanostructures. Chiral structures like helical assemblies and patterned substrates are reviewed as platforms for chiral sensing, with future potential for incorporating semiconductor emitters into plasmonic systems to generate circularly polarized photoluminescence.

Summary: By incorporating stereo-electronic information on synthetic organic building blocks and templates, and utilizing non-directional interactions, achiral constituents can be selectively assembled into complex covalent architectures with multiple stereogenic elements. This proof of concept has implications beyond supramolecular chemistry and could stimulate the on-demand production of highly structured polyfunctional architectures.

Summary: In supramolecular assemblies, the emergence, transference, amplification, and memory of chiroptical activity, including circularly polarized absorbance and circularly polarized luminescence, remain significant challenges. By using hydrogen-bonding interactions, achiral and chiral components can coassemble into helical nanostructures with fine chiroptical activity, which can be remembered in the assemblies even after the removal of chiral additives. The removed chiral elements can be reused to achieve continuous circulation and amplification of chirality in a supramolecular assembly system, providing insight into potential applications in the manufacturing of chiroptical materials.

Summary: Chirality is a property that depends on specific symmetries. This study quantifies chirality using Hausdorff distances and continuous chirality measures and discusses its impact on bulk solids and surfaces. The study proposes using optical circular dichroism in the angular distribution of photoelectrons to distinguish the handedness of chiral solids and their surfaces. The importance of chirality is also discussed in the context of crystal structures, band structure, and the Berry curvature.

Summary: The chitin-based cuticle of beetles with twisted structures have specific optical characteristics that can be transcribed into cholesteric liquid-crystal oligomers under experimental conditions, which can be time-tunable in color with thermal annealing. By observing the internal morphology with transmission electron microscopy, different spectral bands and reflection colors can be achieved. These materials can be used to create smart reflective labels that record the product conservation history and temperature information.

Summary: The study successfully induced chirality in a metal-organic framework built from achiral precursors, with the chiral generation process controlled by the amount of pyridine and temperature. The targeted modification of pyridine selectively leads to controlled chiral orientation and distribution of the bulk samples of the framework.

Summary: Chiral nanoporous nanoarchitectures built from achiral molecules on Ag(100) exhibit diverse shapes and sizes with strict chirality correlation between nanopores and their vertices. The chiral vertices within networks are dimeric, trimeric, or tetrameric, and enantiomeric vertices of one-pair nanopore enantiomers are always in identical type but opposite handedness. These chiral nanopores could potentially serve as templates for surface reaction, chiral recognition, and other applications.

Summary: This article introduces a novel strategy for constructing polymer particles with permanent chirality by partially cross-linking azobenzene units. The destroyed helical superstructure can be perfectly recovered by storing the chiral information and simple heating-cooling treatment or visible light irradiation.

Summary: Strong upconverted circularly polarized luminescence can be achieved from achiral core-shell upconversion nanoparticles (UCNPs) via plasmonic chiral metasurface-induced optical chirality transfer. In the UCNPs-on-metasurface composite, significant enhancement and circular polarization modulation of upconversion luminescence can be achieved, paving new pathways to potential applications in imaging, sensing, and anticounterfeiting fields.

Summary: This study demonstrates strong upconverted circularly polarized luminescence in achiral nanomaterials through plasmonic chiral metasurface-induced optical chirality transfer. By spin-coating core-shell upconversion nanoparticles (UCNPs) on the chiral metasurface, enhanced upconversion luminescence and circular polarization modulation can be achieved.

Summary: This study demonstrates the observation of chiral induced spin selectivity (CISS) effect in supramolecular polymers exclusively containing achiral monomers. The spin polarization correlates with the intensity of the CD spectra of the polymers, indicating a nonlocal effect. Furthermore, temperature dependence studies provide support for the contribution of phonons to spin polarization.
