A Modular Low‐Cost 3D Uniformly Illuminated Mini‐Photoreactor with Versatile In‐Situ Analysis

Advanced Optical Materials, EarlyView.
A “green” Do‐It‐Yourself (DIY)‐realizable mini‐photoreactor made from cheap commercially available parts delivers unprecedented 3D uniform illumination with minimal wastage of photons, and additionally permits in situ much‐demanded analytical tools (absorption, fluorescence, and NMR spectroscopy).

Chiral Sensing of Amino Acids under Visible Light via Hydroxypropyl Cellulose Gels

Advanced Optical Materials, EarlyView.
Hydroxypropyl cellulose gels enable visible‐light‐based chiral detection of amino acid enantiomers. This study showcases their structural color properties for distinguishing phenylalanine and alanine enantiomers. The gels exhibit pH‐responsive color changes, high sensitivity at low concentrations (0.2 wt.%), and long‐term stability, offering ...

Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

Advanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Au(I)‐Catalyzed Regiodivergent Hydroarylation of Allenes for the Synthesis of Tetrahydrodiazepines or Tetrahydrodiazonines

Advanced Synthesis &Catalysis, EarlyView.
Abstract Allenes tethered to pyrroles undergo Au(I)‐catalyzed hydroarylation leading to tetrahydrodiazepines or tetrahydrodiazonines. The regioselectivity of the reaction is governed by both the substitution pattern of the allene and the nature of the Au(I) ligand. Hence, alkyl‐gem‐disubstituted allenes preferentially lead to tetrahydrodiazepines via 7‐
