In their work reported on page 254, Al Mousawi and colleagues propose flavones that can be derived from natural products as versatile high performance visible light photoinitiators for free radical polymerization (meth)acrylates upon near UV light or visible light exposure using Light Emitting Diodes. High polymerization initiating abilities are found and high final reactive function conversions are obtained. The flavones utilization as materials for 3D printing is especially carried out for 1 mm thick 3D printed photopolymers. A full picture of the included photochemical mechanisms is provided. This work paves the way for the development of photoinitiating systems based on natural compounds.
