Design, Synthesis, Characterization And Properties Of Organosilicon Precursors

Based on the investigation of a great deal of related literature, the synthetic methods of organosilicon compounds were briefly summarized, and the recent progress on organosilicon compounds was reviewed in detail. Five functional organosilicon precursors were synthesized, their photoelectron properties were studied, and the synthetic methods of organosilicon compounds were investigated.1. Five photoelectron functional compounds were synthesized, all the compounds mentioned above were characterized by IR, UV-vis, 1H-NMR, MS spectra and elemental analysis. Three compounds have been obtained and determined by single-crystal X-ray diffraction method, the structures were described.2. The electronic spectra of the compounds mentioned above in different solutions were compared.3. Thermal stabilities of the compounds were studied by thermo-gravimetric-analysis. The results indicted that most of them have higher thermal stability, of them, the lowest thermal decomposition temperature is 171℃.4. Electrochemical properties of the compounds were studied in detail by cyclic voltammetry (CV), differential pulse voltammetry (DPV), and the mechanisms of polymerization were discussed, the results showed that target compounds have excellent electrochemical properties; the relationships between properties and structure were also studied.5. Two synthetic methods of organosilicon compounds were adapted. Comparing the merits and demerits of the two methods, we found that it is convenient to use Grignard reagent in the reaction in almost same yield.6. A simple device, whose instruction was offered, was designed and was adaptable to the experiment without water and oxygen system.
