Abstract Chiral metal–organic frameworks (MOFs) have gained rising attention as ordered nanoporous materials for enantiomer separations, chiral catalysis, and sensing. Among those, MOFs are generally obtained through complex synthetic routes by using a limited choice of reactive organic precursors the primary linkers or auxiliary ligands. Here, we report template‐controlled synthesis from achiral grown on nematic cellulose‐derived nanostructured bio‐templates. We demonstrate that MOFs, specifically, zeolitic imidazolate framework (ZIF), unc ‐[Zn(2‐MeIm) 2 , 2‐MeIm=2‐methylimidazole], can be regular within organized nanocelluloses via directed assembly twisted bundles cellulose nanocrystals.

Abstract Handedness is an essential attribute of chiral nanocrystals, having a major influence on their properties. During chemical growth, the handedness nanocrystals usually tuned by selecting corresponding enantiomer molecules involved in asymmetric often known as inducers. We report that, even using same inducer enantiomer, gold can be reversed Au nanorod seeds with either single crystalline or pentatwinned structure. This effect holds for growth induced both amino acids and micelles. Although it was challenging to discern morphological L ‐cystine‐directed particles, electron tomography, cases showed circular dichroism bands opposite sign, nearly mirrored chiroptical signatures micelle‐directed along quasi‐helical wrinkles inverted handedness. These results expand toolbox that might exploited yield host interesting morphologies tunable optical

Precisely controlling the morphologies of plasmonic metal nanoparticles (NPs) is great importance for many applications. Here, a facile seed-mediated growth method demonstrated that tailors Au@Ag NPs from cubes/cuboids to chiral truncated cuboids/octahedra, well-defined octahedra, and tetrahedra, via simply increasing concentrations AgNO3 cysteine in halide surfactant systems. Accordingly, particle symmetries are also tuned. The quite robust where seeds with distinct shapes including irregular ones can all lead uniform NPs. evolution these be illustrated by recently proposed symmetry-based kinematic theory (SBKT). Furthermore, SBKT shows strategy optimize preparation chiral/dissymmetric NPs, experimental results confirm such dissymmetric synthesis strategy.

Subnanometer materials (SNMs) refer to nanomaterials with a feature size close 1 nm, similar the diameter of single polymer, DNA strand, and cluster/unit cell. The growth assembly subnanometer building blocks can be controlled by interactions at atomic levels, representing limit for precise manipulation materials. size, geometry, flexibility 1D SNMs inorganic backbones are polymer chains, bringing excellent gelability, adhesiveness, processability different from nanocrystals. ultrahigh surface atom ratio results in significantly increased energy, leading significant rearrangement atoms. Unconventional phases, immiscible metal alloys, high entropy few layers stabilized, spontaneous twisting may induce intrinsic structural chirality. Electron delocalization also emerge subnanoscale, giving rise enhanced catalytic activity.
