The aim of this work was to investigate the influence of the nanocofinement on the behaviour of organic substrates embedded in mesoporous silicas. This research hinged on two parts. The first study focused on the efficiency of the fragmentation reaction of confined alkoxyamines, under thermal or photochemical activation. Thanks to the comparison with the very same reactions in solution, the quantitative EPR measurements showed that the confinement of organic precursors had no effect on the efficiency of these reactions. Secondly, organic-inorganic hybrid materials were synthesized. These mesoporous silicas were functionalized with diazene radical precursors. Upon 360 nm irradiation, they generated heteroatomic radicals. Different materials were prepared, including one which enabled to form a face-to-face pair of different radicals, i.e. an aryloxyl radical in front of an arylsulfanyl radical. Studies carried out by continuous and pulsed wave EPR enabled to highlight the high stability of these confined paramagnetic species and to measure their relaxation times

The aim of this work was the development of hybrid mesoporous silicas composed with high concentration of embedded transient radicals in order to use them as polarizing agent in DNP-NMR. First of all, quantitative yield in paramagnetic centers were obtained from unimolecular processed carried out under photoirradiation. The synthesis and optimization of photolysis conditions allowed to obtain functionalized silicas by transient radicals from good to quantitative yields. The reactivity difference of radical precursors was rationalized by the fragmentation mechanism and environmental constraints inside the walls of the silica structure which provided high yields. Polyradical systems were characterized by EPR spectroscopy. High life-time allows the evaluation of these new "persistent" radical species as polarizing agent for DNP-NMR

Herein, we combined with nano-synthesis technology and biomedical applications. We present an aqueous based facile microwave-assisted synthesis of carbon quantum dots, which has short synthesis time, low toxicity, water dispersibility and biocompatibility. These advantages are beneficial for biological application. The red, yellow, green and blue fluorescent carbon dots were successfully synthesized by adjusting the heteroatomic doping and changing the purification method. Furthermore, we applied these carbon dots for in vitro antioxidant activity and bioimaging. Part Ⅰ: Antioxidant activity of phosphorous and manganese element co-doped red magnetofluorescent carbon dots P-phenylenediamine was used as carbon precursor. Doping phosphorous (P) heteroatom into Cdots could enhance the quantum yield. Furthermore, doping manganese (Mn) could impart magnetic property to carbon dots. The red fluorescent carbon dots were successfully synthesized by one-pot microwave method. In this study, the application of antioxidant property for PMn@Cdots was carried out by using DPPH, •OH and O2-•, respectively. The result was compared with ascorbic acid and it showed that PMn@Cdots also have good antioxidant property. Furthermore, in the protective activity result of H2O2-induced cell death model, it was found that PMn@Cdots-HA could reduce intracellular ROS levels and protect cells from oxidative stress.
