Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Long‐Range Spin Transport in Chiral Gold

Advanced Materials, EarlyView.
It is demonstrated that in chiral gold film, spin information can be transferred to distances of several microns at room temperature. The conduction of spins is accompanied by the Hall effect that exists without applying an external magnetic field. The spin diffusion length is consistent with the frequency‐dependent Hall effect which indicates spin ...

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

Advanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Pseudo‐Dichroism: Nanophotonic Induction of Chiroptical Activity in Symmetric Molecular Systems

Advanced Optical Materials, EarlyView.
By analyzing vibrational circular dichroism (VCD) spectra of chiral nanomaterials, we distinguish genuine molecular chirality (true dichroism) from measurement artifacts (pseudo dichroism) using a novel, robust framework. The spectral criteria we establish apply broadly to all chiroptical techniques in nanomaterial research, enhancing precision in ...

Enzymatic Synthesis of Enantiopure (R)‐Citronellal from Geraniol via a Short‐Chain Dehydrogenase and Ene Reductase

Advanced Synthesis &Catalysis, EarlyView.
A synthetic cascade with two consecutive biocatalytic steps consisting of a short‐chain alcohol dehydrogenase and an ene reductase in a biphasic system provides (R)‐citronellal with >90% conversion and >99% enantiomeric excess from inexpensive geraniol. The development of synthetic routes to produce enantiopure (R)‐citronellal as a key intermediate for

Asymmetric Synthesis of Highly Substituted Spiro[2H‐pyrrole‐2,3‐Succinimide] Derivatives by Copper‐Catalyzed Post‐Ugi Reactions

Advanced Synthesis &Catalysis, EarlyView.
Abstract Herein we present a novel one‐pot methodology for the synthesis of enantioenriched 2H‐pyrrolespirosuccinimides by copper‐catalyzed reactions on Ugi adducts derived from enantiopure α‐alkylbenzyl amines through a chirality transfer process. We have proposed a mechanism, supported by density functional theory (DFT) calculations, where a hydrogen

Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

Advanced Synthesis &Catalysis, EarlyView.
An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.
