Photo Amphoteric Compound Generators for Environmentally-friendly Materials

Photo amphoteric compound generators (PAmGs), which are onium salts used to generate 2-aminoethane-1-sulfonate (taurine) in photo decomposition, were prepared as a mixture and compared with the absorption spectra, photo generation of taurine, and photo pH changes in aqueous solution. One of these ph...

Description
Summary:Photo amphoteric compound generators (PAmGs), which are onium salts used to generate 2-aminoethane-1-sulfonate (taurine) in photo decomposition, were prepared as a mixture and compared with the absorption spectra, photo generation of taurine, and photo pH changes in aqueous solution. One of these photo taurine generators (PtaurineGs) with bis(4-methoxyphenyl)iodonium was designed and prepared for environmentally-friendly photo-reactive materials. These PtaurineGs were water-soluble and photo-decomposable. The photo induced gelling of the aqueous solution drop including casein, which were derived from natural compounds, were demonstrated for stereolithography.
