Visible light promoted thiol-ene reactions using titanium dioxide.
The radical addition of thiols to alkenes is reported under photoredox conditions, using visible light and TiO2 as a cheap and readily available photocatalyst.
متن کاملHyaluronic Acid Hydrogel Materials
This chapter discusses two protocols that are used throughout the remaining chapters. These protocols and experimental data comprise the early preliminary work of this dissertation. The first protocol is the synthesis of photocrosslinkable glycidyl methacrylate modified hyaluronic acid (GMHA). This derivative was synthesized by the reaction of glycidyl methacrylate with HA in a solvent mixture ...
متن کاملRedox Mediators in Visible Light Photocatalysis: Photocatalytic Radical Thiol–Ene Additions
Synthetically useful radical thiol-ene reactions can be initiated by visible light irradiation in the presence of transition metal polypyridyl photocatalysts. The success of this method relies upon the use of p-toluidine as an essential additive. Using these conditions, high-yielding thiol-ene reactions of cysteine-containing biomolecules can be accomplished using biocompatibile wavelengths of ...
متن کاملVISIBLE-LIGHT-ACTIVE NITROGEN DOPED TIO2 NANOPARTICLES PREPARED BY SOL-GEL ACID CATALYZED REACTION
Yellow-colored nitrogen doped TiO2 photocatalyst and a pure TiO2 powder were synthesized via sol-gel method using TiCl4 and urea as raw materials. However, the synthesis procedure for nitrogen doped TiO2 was catalyzed by acid that dialed with controlled precipitation and slow nucleation. According to XRD analysis, the nitrogen doped TiO2 consisted of anatase phase of titania which was a signifi...
متن کاملVisible light-initiated interfacial thiol-norbornene photopolymerization for forming islet surface conformal coating.
A cytocompatible visible light-mediated interfacial thiol-norbornene photopolymerization scheme was developed for creating hydrogel conformal coating on pancreatic islets. The step-growth thiol-norbornene reaction affords high consistency and tunability in gel coating thickness. Furthermore, isolated islets coated with thiol-norbornene gel maintained their viability and function in vitro.
