Electronically tuned triazole-derived mesoionic carbenes enhance the stability of Ag and Cu nanoparticles.
Stabilizing silver and copper nanoparticles remains a persistent challenge due to their rapid oxidation and surface degradation under ambient conditions. Ligand engineering offers a powerful strategy to control nanoparticle stability; however, N-heterocyclic carbenes (NHCs), including mesoionic NHCs (mNHCs), despite th...
