| Abstract |
Thiol-ene click reaction is highly efficient and rapid reaction to achieve quantitative yield with no side reaction. The reaction can be triggered by photoredox catalysis in the presence of dye molecules. Among a variety of dye molecules, Eosin Y has attracted attentions as a photoredox catalyst because it is metal-free and hence, environment friendly, commercially available with low cost, efficient in photocatalysis due to its high quantum yield at visible light wavelength range. We demonstrate the photocatalysis with visible light illumination to modify reactive copolymers having various alkene groups which can be functionalized with thiol containing molecules. The postpolymerization modifications in this study emphasize the potential of visible light-mediated thiol-ene click chemistry to accomplish target structures in polymeric materials towards desired physical and chemical properties. |
