Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Self‐Oscillation in Photochromic Thiazolothiazole‐Embedded Polymers

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
Experimental observation of redox‐driven self‐oscillations at the soft‐matter/ambient interface of a photochromic thiazolothiazole‐embedded polymer by spectroscopic ellipsometry. The self‐oscillations are facilitated by a reversible electron transfer cycle involving the thiazolothiazole unit, a cross‐linked polymer matrix, and ambient molecular oxygen.
