The present invention relates to the field of covalent printing. More particularly it relates to cyclopropenone derivatives (ink compounds), their use in a covalent printing process and their synthesis process. The invention also relates to a covalent printing process comprising a step of reacting an ink compound according to the invention with a functionalized cellulose sheet comprising -N 3 functional groups. On other aspects the invention also encompasses covalently printed paper sheets.
It's alive: A ring‐strained alkyne based on dibenzo[a,e][8]annulene undergoes ring‐opening metathesis polymerization (ROMP) to give a high‐molecular‐weight poly(ortho‐phenylene) featuring alternating ethyl and ethynyl linkers along the polymer backbone. The molybdenum‐alkylidyne‐based catalyst system discriminates between strained and unstrained alkynes to yield a living polymer with an unparalleled
