| 摘 要： | 以高含氢硅油(甲基氢硅油)为原料,在Lamoreaux催化剂作用下,先与N-烯丙基咔唑进行硅氢加成反应,再与4-乙烯基环氧环己烷反应,合成了折射率达1.577的脂环型环氧有机硅预聚体(Ep-Cz-SiO)。Ep-Cz-SiO的结构由1H NMR和IR表征,并确定了分子中咔唑基团的含量。咔唑基团的引入显著提高了环氧有机硅预聚体的折射率。热重分析表明,所制备的带有咔唑基团的脂环族环氧有机硅预聚体的热稳定性高于含氢硅油原料。

| Abstract: | Cycloaliphatic epoxy-silicone oligomer(Ep-Cz-SiO)with 1.577 of refrative index was synthesized via sequential hydrosilylation reactions of methylhydrogen silicone oil by attaching first N-allyl carbazole,followed by 4-vinyl-1-cyclohexene-1,2-epoxide in the presence of Lamoreaux catalyst.Ep-Cz-SiO was characterized by 1H NMR and IR.The refractive index of the obtained monomer were measured and the results showed that the carbazole ring can improve RIs.Thermal analysis showed that Ep-Cz-SiO had better thermal stability than methylhydrogen silicone oil. |

| Keywords: | cycloaliphatic epoxy-silicone hydrosilylation carbazole synthesis refractive index |
