제목 Synthesis of Periodic Mesoporous Organosilicas with Bridged Bisimine Units within the Framework
초록 In this work, we have synthesized bissilylated organic fragment with diimine bridge. The successful synthesize of organosilane precursor was confirmed by 1H and 13C NMR and FT-IR spectroscopic analyses. The diimine bridged precursor was distributed in the framework of the periodic mesoporous organosilica materials via a surfactant-templated route by co-condenzation of an organosilane precursor and tetraethylorthosilicate (TEOS), using triblock copolymer (Pluronic P123) as a structure directing agent. The mesoporosity and long-range order of the material was confirmed by powder X-ray diffraction, N2 sorption isotherms and transmission electron microscopy (TEM). The presence of organic precursor in the framework was further confirmed by FT-IR, 29Si and 13C CP MAS NMR spectroscopic analyses, and Thermogravimetric analysis (TGA). The functionalization represents a useful tool to fine-tune hybrid materials for a wide range of applications, including adsorption, catalyst and sensors.
