📢 Bringing to light a new surface reaction💡

We imaged a stable, surface-supported nitrene synthesized through azide photolysis on Au(111) ⚡

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.
