Pressure‐Induced Structural and Optoelectronic Modulations in 2D Dion‐Jacobson Hybrid Lead Iodide Perovskites With a Rigid Spacer

Advanced Optical Materials, EarlyView.
Compression to ≈2.0 GPa results in a non‐monotonic enhancement of the Pb‐I bond distortion, rarely observed in other 2D lead‐iodide hybrid perovskites. The octahedral distortion together with the rigidity of spacer cation are found to play a dominant role in determining the optoelectronic properties of DPDAPbI4 under high pressure.

In Situ Photopolymerization of Smectic B Liquid‐Crystalline Electrolytes from Mesogenic Phosphate–Diacrylate/Ionic Liquid Complexes for High‐Performance Soft Ionic Actuators

Advanced Robotics Research, EarlyView.
A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

Redrawing the Mannich‐Type Reaction through Carbonyl Umpolung Reactivity

Advanced Synthesis &Catalysis, EarlyView.
GA: Herein, a conceptually novel one‐pot multicomponent strategy is reported for the streamlined construction of five‐membered imidazolidines from 1,2‐diaza‐1,3‐dienes (onefold), amines (twofold), and formaldehyde (twofold). This redesigned Mannich‐type reaction that exploits a carbene‐like activity of 1,2‐diaza‐1,3‐dienes (realized by “umpolung ...

One‐Pot Cascade Synthesis of Isoquinolinone‐Fused Quinoxalines Through Sequential Rh(III)/Pd(II) Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A new one‐pot, dual catalytic strategy for the synthesis of polycyclic isoquinolinone‐fused quinoxalines from commercially available N‐(2‐acetamidophenyl)benzamides and 1,3‐diynes is reported. This transformation proceeds via Rh(III)/Pd(II)‐mediated sequential NH/CH activation/annulation. Detailed mechanistic studies elucidate the reaction pathway. A

Naphthalimide Derivatives as Film‐Based Fluorescent Sensors for Rapid Detection of Illicit Drugs

Advanced Sensor Research, EarlyView.
Four novel 1,8‐naphthalimide (NI) derivatives for the detection of illicit drugs with different substituents at the 4‐position are reported. Their contrasting fluorescence responses enables five illicit drugs to be distinguished from interferents with a mean classification accuracy of 81%.

Discovery of Surface‐Induced Resonance Shift of 4‐Nitrophenol Enabling Direct Monitoring of an Enzymatic Reaction

Advanced Sensor Research, EarlyView.
A surface‐modified porous silica consisting of acetyl‐protected mannose residue and co‐precipitated urea compounds promotes a distinct resonance shift of 4‐nitrophenol under neutral conditions upon interaction, that is revealed by confocal Raman spectroscopy. The quinone‐type resonance structure is favored over the phenol‐type.
