Hybrid organic-inorganic macromolecular photoinitiator system for visible-light photopolymerization

- Amino-functionalized macromolecular photoinitiator for visible-light was synthesized.
- Hybrid organic-inorganic photoinitiator (OI-AH) was synthesized by sol-gel process.
- Hydrolytic condensation of amino-functionalized silane resulted in bulky OI-AH.
- The camphorquinone/OI-AH pair is very attractive for polymerization of methacrylates.
