D–A–π–A Fused Pentacyclic Organic Dyes as Sensitizers for Dye‐Sensitized Solar Cells Operating under Low‐Light Conditions

ChemistrySelect, Volume 11, Issue 30, 10 August 2026.
The highly conjugated [1]benzothieno[3,2‐b]thieno[2,3‐f][1]benzothiophene (TBTBT) moiety was introduced for the first time as a mild donor group in the structure of three D‐A‐π‐A organic dyes. The compounds were prepared through appropriate multistep synthetic sequences and fully characterized. Dye‐sensitized solar cells fabricated with the new dyes as

On the Stereoselective Behavior in the Photochemical Paternò–Büchi Reaction of Benzophenone With Phenyl‐(2‐furyl)Methanol

ChemistrySelect, Volume 11, Issue 31, 17 August 2026.
Hydrogen bond formation determines stereoselectivity in photochemical reaction allowing the formation of complexes between the reagents and these complexes determine the stereochemistry of the product. ABSTRACT Paternò–Büchi reaction between benzophenone and phenyl‐(2‐furyl)methanol gave the corresponding oxetane with high stereoselectivity.

Contact Sensitization in Patients With Frontal Fibrosing Alopecia: Patch Test Results With an Extended Baseline Series in Consecutive Patients

Contact Dermatitis, Volume 95, Issue 2, Page 192-199, August 2026.
Sensitization to propolis, shellac and gallate mix is FFA‐associated, but its relevance is largely unknown. Sensitization to salicylates is frequent and associated with symptoms of intolerance to sun exposure or sunscreens. No significant improvement by allergen avoidance is identified.

Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.
