It is reported that efficient photoinitiators, suitable for two-photon polymerization, can be obtained using the copper catalyzed azide/alkyne cycloaddition reaction. This click chem. strategy provides a modular approach to the assembly of photoinitiators that enables the rapid variation of key fragments to produce photoinitiators with desirable properties. To assess the performance of the first-in-class photoinitiators generated by this approach, a screening method is developed to enable the rapid determination of polymerization and damage thresholds in numerous photoresists during two-photon polymerization The degree of consumption of vinyl groups (DC) and homogeneity of the polymerization are further assessed by micro-Raman spectroscopy. Finally, more complex structures are fabricated to demonstrate that the efficient two-photon polymerization of stable 3D microarchitectures can be achieved using triazole-based photoinitiators. In the part of experimental materials, we found many familiar compounds, such as Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Product Details of 510758-28-8)
Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8) can stabilizes Cu(I) towards disproportionation and oxidation thus enhancing its catalytic effect in the azide-acetylene cycloaddition.Product Details of 510758-28-8Polytriazolylamines were synthesized by the copper(I)-catalyzed ligation of azides and alkynes.
