Manufacture of solid chiral material and measurement of its polarity response

利用溶胶 凝胶低温合成非晶态技术 ,以正硅酸乙酯、γ 缩水甘油醚基丙基三甲氧基硅烷和乙醇为前驱体 ,将手性分子葡萄糖均匀地掺入到上述体系的溶胶与凝胶中 ,成功地研制出无机固体手性材料样品 ,并对其光学极化特性、光谱特性及材料的热稳定性进行了测试 .测试结果表明 ,样品的旋光率为 - 0 95° cm ,计算所得的手征参数为1 5 5× 10 - 7.

Using TEOS, KH560 and C2H5OH as precursor, the chiral molecule C6H12O6 was uniformly synthesized into the gel by sol-gel process. So a solid chiral material has been manufactured successfully. The polarity response, optical spectrum and heat stability have been tested. The result shows that its specific rotation is -0.95degrees/cm and its chiral parameter is 1.55 x 10(-7).
