Enhancement in the initiating activity of chalcones a long-alkyl chain strategy for free radical photopolymerization and 3D printing
A novel chalcone-based derivative, E -PHMTO, equipped with an alkyl chain and chemically similar to the commercial photoinitiator ITX, was successfully synthesized. Compared to the intermediate reaction products E / Z -HMTO, the introduction of an alkyl chain to the chalcone group shifts the focus o...

/
Z
-HMTO, the introduction of an alkyl chain to the chalcone group shifts the focus of
E
-PHMTO towards proton transfer rather than isomeric side reactions, resulting in an LED-sensitive photoinitiator with excellent initiating performance through steric hindrance. Furthermore,
E
-PHMTO demonstrated superior initiating activity compared to ITX under LED@385 nm irradiation and proved to possess outstanding polymerization properties suitable for 3D photo-printing applications. This research might offer a versatile approach for the convenient design and preparation of highly efficient, LED-sensitive chalcone photoinitiators.
