摘要： 以1,1,3,3-四甲基-1,3-二乙烯基二硅氧烷为起始原料,分别与1-丙硫醇、硫代乙醇酸、巯基丙酸、巯基丙酸甲酯进行巯-烯“点击”反应,制备了4种含硫官能基二硅氧烷:1,1,3,3-四甲基-1,3-双(2-(丙硫基)乙基)二硅氧烷、3,3'-(1,1,3,3-四甲基二硅氧烷-1,3-二乙基硫醚基)双乙酸、3,3'-(1,1,3,3-四甲基二硅氧烷-1,3-二乙基硫醚基)双丙酸、3,3'-(1,1,3,3-四甲基二硅氧烷-1,3-二乙基硫醚基)双丙酸甲酯。采用IR、NMR、GC-MS等方法对产物结构进行了表征。研究结果发现,合成的化合物在紫外-蓝光区有着强而窄的荧光发射,使得它们在光学器件方面有潜在的应用价值。
Abstract: Using divinyltetramethyldisiloxane(MMVi)as the starting materials, a series of functionalized disiloxanes(S1-S4)have been synthesized between MMVi and four types of thiols(propanethiol, mercaptoacetic acid, thiohydracrylic acid, and methyl 3-mercaptopropionate)via facile thiol-ene “click” reaction and characterized by NMR(1H, 13C)and mass spectroscopy. Their luminescent properties were characterized by Fluorescence Spectrometer and show strong and narrow emission peak, which means these compounds could be applied in optical devices
