•Vanillin can be used as a scaffold for the synthesis of type I photoinitiator.•Vanillin-derived type I photoinitiator generates highly reactive radical species.•Vanillin-derived photoinitiator induces free-radical photopolymerization.
A new efficient type I photoinitiator derived from vanillin was synthesized to initiate, according to a green photoinduced process, the free-radical polymerization (FRP) of acrylate monomers in a reduced time and under air. Interestingly, this unprecedented photoinitiator lead to high acrylate conversions even under air, with a higher efficiency than some reference photoinitiating systems commonly used in FRP.
