From Supramolecular Order to Device Performance in Langmuir–Blodgett and Langmuir–Schaefer Films

ChemNanoMat, Volume 12, Issue 5, May 2026.
This review delves into the theoretical fundamentals and key methods for the electrical and electrochemical characterization of Langmuir–Blodgett (LB) and Langmuir–Schaefer (LS) films, with a particular emphasis on the precise nanostructuring control these techniques offer. By analyzing a selection of influential studies—ranging from early foundational

Selenium‐Bearing Conducting Polymer/Graphene Quantum Dot Hybrid for Enzyme Based Electrochemical Biosensor Targeting Tyrosinase Inhibition Via Rosmarinic Acid

ChemistryOpen, Volume 15, Issue 5, May 2026.
In this present study, an enzyme‐based amperometric nanobiosensor was designed and fabricated through the immobilization of tyrosinase onto a selenium‐bearing conducting polymer (poly[BDT‐alt‐(TP;BSe)]), in combination with NH2‐functionalized graphene quantum dots incorporating benzoselenadiazole, thienopyrroledione, and benzodithiophene moieties.

Boosting 2D Black Phosphorus Ambient Stability: Noncovalent Functionalization Using Viologen Molecules

Small, Volume 22, Issue 25, 4 May 2026.
Viologen derivatives are employed to tackle BPNS oxidation challenges through a noncovalent strategy. Comprehensive characterization techniques, complemented by DFT calculations, provide detailed insights into these interactions. Notably, XPS analysis reveals that MV‐BPNS hybrids experience minimal oxidation under ambient conditions, highlighting the ...

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Investigation of Potential Risks in Bio‐Based Food Contact Materials (FCMs) From Microbial Exploitation of Agricultural Wastes: Case Studies of Bacterial Cellulose and Nisin

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT In the context of the circular economy and the increasing demand for safe and sustainable packaging, this work addresses the safety assessment of food contact materials (FCMs) derived from agro‐industrial by‐products. Despite growing interest in these bio‐based materials, the literature still lacks a structured safety‐assessment framework able

Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.

Synthesis, Structure, and Thin Film Optical Properties of a Chiral Benzothiazole‐Derived Squaraine

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Solution‐processed thin films can be sensitive to the choice of solvent and thermal annealing, which we explore for a chiral benzothiazole squaraine. We observe peculiarly shaped excitonic circular dichroism in uniaxially anisotropic thin films, in which the presumed Davydov bands are spatially distributed exclusively into in‐plane (UDC) and out‐of ...

Highly Active CH Bond Borylation of Aromatics With Pyridine as Convenient, Low‐Cost Ligand Under Iridium Catalysis

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
The highly atom‐economy iridium‐catalyzed CH bond borylation of aromatics has been achieved utilizing simple and trivial pyridine as the ligand, which is 2–3 orders of magnitude cheaper than the current state‐of‐the‐art ligands, thus significantly reducing both the E‐factor and the carbon footprint associated with tedious and waste‐generating ligand ...
