In their work reported on page 1791, Joo and colleagues found formulations comprising an Ru‐based catalyst supported by a salicylaldimine, a photoacid generator (PAG), and a monomer to be inert and stored for periods of time. Exposure of the mixture to UV light caused the PAG to generate an acid, which activated the catalyst and promoted ring‐opening metathesis polymerization reactions. Formulations that contained cyclooctadiene or dicyclopentadiene were tested in combination with a variety of PAGs and integrated into nanoimprint lithography (NIL) resists. The resists were used in proof‐of‐principle demonstrations to replicate nanometer‐sized patterns from a transparent template. (DOI: 10.1002/pola.29449 )
