First Access to Tetraazadiindenopyrenes via Selective Pyrrole Cyclization of Phenyl‐Substituted Tetraazapyrene Derivatives on Au(111)
Contrary to long-held expectations of on-surface chemistry, tetraphenyl-substituted tetraazapyrene undergoes selective pyrrole cyclization and C–C coupling on Au(111), forming a distinctive N-doped n...

📢 Bringing to light a new surface reaction💡 We imaged a stable, surface-supported nitrene synthesized through azide photolysis on Au(111) ⚡ with @grilllab.bsky.social Read more on @angewandtechemie.bsky.social 🔗 onlinelibrary.wiley.com/doi/full/10....
we report the formation of a stable, surface-supported dinitrene achieved through the photolysis of a diazide precursor on an Au(111) metal substrate. We combine high-resolution scanning probe techniques with theoretical calculations, providing the first real-space imaging of a metal nitrene adsorbed on a surface and exploring the associated photoreaction mechanism.
