Patterns of Gold Nanoparticles on Cholesteric Surfaces

Small Structures, Volume 7, Issue 4, April 2026.
Polymer‐stabilized cholesteric liquid crystal (PSCLC) films feature arches that guide the self‐assembly of gold nanoparticles (AuNPs) into large‐scale arch‐shaped architectures. This organization stems from a balance between AuNP anchoring and the relief of elastic distortions in the PSCLC, positioning the AuNPs precisely within the valleys of the ...

Privileged Chiral Photocatalysts

Angewandte Chemie, Volume 137, Issue 36, September 1, 2025.
Privileged chiral catalysts have transformed asymmetric synthesis, conferring generality to processes that are routinely leveraged in the construction of societally important functional small molecules. This mini‐review is intended to survey the conception and evolution of privileged chiral photocatalyst scaffolds that enable simultaneous orchestration

Microdroplet Stabilization Enabled Direct Mass Spectrometric Identification of Electrogenerated Transient Carbocation Intermediates

Advanced Science, Volume 13, Issue 9, 13 February 2026.
The in situ mass spectrometric identification of the electrogenerated benzylic and phenylic carbocations, whose half‐lives in bulk solutions are on the nanosecond scale, is achieved by taking advantage of the unique stabilization effect of the electrosprayed microdroplets.

A Comprehensive Review of Acne Treatments: Unpacking the Chemical Structures and Effective Bioactive Compounds

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aims Acne vulgaris is a frequent skin disorder, affecting a large part of the population worldwide, and strongly influencing not only the physical but also the mental aspects of health. The choice of therapy for acne vulgaris is a very difficult one because the multifactorial causality of the disease and interindividual ...

Well‐Defined Rhodium and Iridium Complexes Containing Chiral Cyclic(Alkyl)(Amino)Carbenes for Asymmetric Hydrogenation

ChemistryEurope, Volume 4, Issue 1, January 2026.
A set of fourteen well‐defined rhodium and iridium complexes containing various enantiopure cyclic(alkyl)(amino)carbene (ChiCAAC) ligands (>96% ee to > 99.5% ee) has been synthesized and fully characterized. While no enantioselectivity is observed with chiral Rh‐CAAC, the Ir‐CAAC counterparts demonstrated good performances in the asymmetric ...

Exploring Isophorone‐Based Dienones: Comprehensive Insights Into Their Synthesis, Reactivity, and Diverse Applications

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Isophorone is an important motif in synthetic organic chemistry, as it is highly reactive and can get involved in a diverse array of functional group transformations to access various synthetic intermediates and molecular targets. In this context, an important group of compounds is the conjugated or nonconjugated isophorone‐cored dienones, which are ...

All‐Inorganic InP/ZnSe/ZnS Quantum Dots with Chalcogenidometallate Ligands for Biosolar Catalysis

Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.
Intrinsic charge transfer limitations in core/shell QDs are addressed through a ligand‐induced band offset engineering (LBOE) strategy utilizing metal chalcogenide complex (MCC) ligands. The MCC‐functionalized InP/ZnSe/ZnS QDs exhibited remarkably augmented hydrogen peroxide (H2O2) generation.

Anionic annulation of cross‐conjugated‐carbonyl systems with 2,3‐dichloro‐5,6‐dicyanobenzoquinone

Journal of the Chinese Chemical Society, Volume 72, Issue 12, Page 1605-1610, December 2025.
DDQ serves as a dicyanoacetylene surrogate in a novel annulation with α‐EWG‐activated cross‐conjugated carbonyl systems, enabling direct and efficient access to dicyanobenzene products. Abstract We report a base‐mediated annulation of α‐EWG‐activated enone systems with 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ), affording dicyanobenzene derivatives via

Synthesis of Poly‐Substituted Imidazo[1,2‐a]Pyridines via a Double Annulation Strategy

Asian Journal of Organic Chemistry, Volume 14, Issue 11, November 2025.
Herein, we report a novel and efficient synthetic strategy for the construction of poly‐substituted imidazo[1,2‐a]pyridines from the reaction of enaminonitriles with propargylamines via a domino conjugate substitution–nucleophilic addition‐cycloisomerization process.
