Summary: Metal naphthalocyanines (MNcs) have been demonstrated as efficient photocatalysts for controlled polymerization reactions. Due to their lower redox potential, they exhibit a unique selectivity in activating trithiocarbonate RAFT agents, depending on the nature of the R group. Furthermore, by adjusting the reaction temperature, the activation barrier for trithiocarbonates with a secondary R group can be overcome.

Summary: 3D printing technology allows for easy production of geometrically complex materials, and this study presents a method of post-functionalizing these materials using the 3D printer hardware. By controlling the chemical composition of the resin, the bulk and interfacial properties of the 3D printed materials can be independently modified. The process involves preparing liquid resins, curing them in layers using a 3D printer, and replacing the initial resin with a new mixture containing functional monomers. This allows for the production of a wide range of 3D printed materials with tailorable properties.
