Chirality communications between inorganic and organic compounds

Abstract

Chirality communications between inorganic and organic compounds bridge the gap between different materials. The transfer is mainly realized by material hybridization andasymmetric synthesis, while the recognition is usually carried out in the form of enantioselective adsorption of organics on inorganics. The transfer and recognition can enlarge the number of chiral materials, which may lead to new applications in many fields.

Chiroptical Transitions of Enantiomeric Ligand‐Activated Nickel Oxides

“…However, a systematic exploration of such factors is lacking because i) the controlled synthesis of chiral TMO NPs using different ligands is still challenging; ii) theoretical explanations on the origins of chiroptic behavior are still imperfect; and iii) relatively little attention has been paid so far to the effects of chiral surface ligands, as the fascinating properties of TMOs themselves continue to produce many interesting findings.

“…However, a systematic exploration of such factors is lacking because i) the controlled synthesis of chiral TMO NPs using different ligands is still challenging; ii) theoretical explanations on the origins of chiroptic behavior are still imperfect; and iii) relatively little attention has been paid so far to the effects of chiral surface ligands, as the fascinating properties of TMOs themselves continue to produce many interesting findings. [3,18] Ligand-induced chirality in transition-metal oxide (TMO) nanostructures have great potential for designing materials with tunable chiroptical effects. Herein, a facile strategy is reported to prepare chiroptical active nickel-oxide hybrids combined with pH adjustment, and the redox treatment results in ligand transformation, which is attributable to multiple optical transitions in the TMO nanostructures.…”

Engineering of inorganic nanostructures with hierarchy of chiral geometries at multiple scales

“…Several extensive reviews on chiral inorganic nanoparticles (NPs) and their assemblies were published over the last few years that described, in various degrees of detail, the chiral nanostructures known today 17–30 . Along with their preparation and optical properties, these works also discuss their potential applications which include but not limited to chiral catalysis, enantiospecific separation, biosensing, chiral memory, and chiroptical devices.…”

Indication of Strongly Correlated Electron Transport and Mott Insulator in Disordered Multilayer Ferritin Structures (DMFS)

“…Chirality in organic structures, such as the ferritin protein shell subunits, has also been observed to function as a spin filter, which would increase the spin coherence of exciton electrons generated by individual ferritin cores in disordered layers of ferritin cores [11]. Likewise, the chirality of inorganic structures such as the ferrihydrite core of ferritin has also been observed to facilitate interaction with chiral organic structures, such as proteins [12]. Furthermore, it has been observed that mixed iron oxide phases are present in the ferritin core that include magnetite regions, which could also contribute to spin filtering [13].…”
