Sentetik uygulamalar için singlet oksijen doldurulabilir kaynaklar olarak silika kaplı demir oksit nanoparçacıklar

In the rapidly developing world of synthetic chemistry, there is a constant need for high-efficient catalyst. Besides this, reusable and easily removable catalysts are highly desired to reduce costs for environmentally friendly synthesis for both synthetic and manufacturing requirements. Magnetic nanoparticles (MNPs) are promising candidates for effortlessly removable structures due to their ability of being removed by magnetic field. Iron oxide nanoparticles have a well distin- guished place among MNPs since they have unique properties and they can be prepared and functionalized easily. Combination of photosensitizers with MNPs is a new approach for synthetic applications due to the fact that singlet oxygen is a reactive specie for various types of reactions. Herein, BODIPY with 2-pyridone moiety on silica coated iron oxide nanoparticle is designed as a magnetically removable nanostructure that can generate, store and release singlet oxygen. The efficiency is studied by the oxidation of organic sulfides to sulfoxides since they are at the core of many biological processes. Furthermore, this design can produce recyclable and reusable catalysts for additional transformations with high efficieny.
