Abstract

Mn, (II), Fe(II) and Co(II) complexes will be synthesized to catalyze Controlled Radical Photopolymerization (CRP2). The proposal extends into three stages, which are completely interconnected in the development process. Initially, the attention will be directed to the Mn, (II), Fe(II) and Co(II) complexes non-symmetric NHCs ligands synthesis. The Mn, (II), Fe(II) and Co(II) complexes will be characterized by FTIR, UV-Vis, Cyclic Voltammetry, EPR, elemental analysis and mass spectrometry. The second stage will be dedicated to the evaluation of the photochemical properties of the Mn(II), Fe(II) and Co(II) NHC complexes. Consequently, the high reactivity of these compounds will be demonstrated through some direct laser write experiments, where high-spatial-resolution 3D patterns will be obtained. Therefore, this research paves the way for the development of new organometallic photocatalysts in CRP2 as well as their applications in 3D printing.
