手性非晶玻璃的合成及其极化特性

Fabrication of Solid-state Chiral Material and its Polarity Response

利用溶胶 -凝胶低温合成非晶态技术 ,以正硅酸乙酯和乙醇为前驱体 ,将手性分子灰黄霉素均匀地掺入到溶胶 -凝胶体系中 ,首次成功地研制出手性非晶态玻璃材料 ,并对其光学极化特性及材料的热稳定性进行了测试。测试结果表明 ,手性非晶态玻璃的旋光率为 - 1.4 5°/ cm,计算所得的手征参数为 2 .37× 10 - 7。

Chiral molecule C17H17ClO6 was firstly incorporated in SiO2 gel by sol-gel process. Its thermal stability was estimated with DTA curve. The polarity response of the obtained gel was investigated and discussed. Results show that its specific rotation is -1.45°/cm and its chiral parameter is 2.37 × 10-7.
