Synthesis and Characterization of Multi-Functional Substituted POSS

Abstract:

Five different multifunctional nitro octaphenyl silsesquioxane (NPS) were Synthesised and reduction was carried out to obtain amino octaphenyl silsesquioxane(APS). These compounds were characterized with elementary analysis, fourier transform infrared(FTIR), nuclear magnetic resonance (NMR, ²⁹Si), wide-angle X-ray diffraction(XRD) and thermogravimetry (TG). Experiental results showed that the longer the nitration time, the more nitro connected to the OPS, but not positively, nitro number remained unchanged after five hours. NPS has good thermal stability than corresponding APS under 450°C, and the thermal stability of APS are decrease with the increase of amino number.
