Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Visible‐Light‐Mediated Synthesis of Biscoumarins Utilizing Photocaged Sulfonic Acid as the Catalyst

European Journal of Organic Chemistry, Volume 29, Issue 37, 1 October 2026.
A mild visible light approach for the synthesis of biscoumarins utilizing arylazo sulfones as the photoacid generator under 467 nm irradiation is introduced. Throughout the years, biscoumarin derivatives, known for their diverse biological properties, have attracted extensive synthetic interest.

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

Macromolecular Rapid Communications, Volume 47, Issue 19, 6 October 2026.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)
