Open sesame : Novel cationic Ru II complexes with N‐heterocyclic carbene ligands (see structure) have been prepared and used as UV‐triggerable photoinitiators for ring‐opening metathesis polymerization. They may be used for the high‐yield synthesis of bulk polymers as well as for surface functionalization. Laser pulse radiolysis and NMR spectroscopy experiments supported by quantum chemical calculations give insight into the initiation mechanism.
