Copper(I) complexes have attracted considerable attention as efficient redox photocatalysts (PCs) in photopolymerization. In this study, two copper(I) bearing a pyridine-benzothiazole ligand were thoroughly investigated for the free radical photopolymerization of ethoxylated trimethylolpropane triacrylate under violet and green light irradiation. A three-component system comprising copper complex, di-tert-butyl-diphenyl iodonium hexafluorophosphate, ethyl dimethylaminobenzoate additives was various conditions. The exhibited remarkable photoinitiation capabilities, achieving high monomer conversion rates highlighting significant structure–reactivity relationships. Based on energy calculations spectroscopic analyses, mechanistic pathway proposed. optimal conditions successfully applied 3D printing, producing smooth uniform structures.
