本文通过对介电常数ε的计算研究了 C6 0 修饰的固体支撑双分子层膜 (s- BL M) ,并与未修饰的 s-BL M的特性进行了比较。研究表明 ,C6 0 修饰的 s- BL M的介电常数 ε=5 .1(在光激发条件下达到 5 .5 ) ,远大于未修饰的 s- BL M的介电常数 (ε=2 .4) ,甚至超过了 C6 0 固体的介电常数。此时 ,C6 0 修饰的 s- BL M对 I-的检测灵敏度提高约 2个数量级。并对其机制进行了分析。分析表明处于超分子结构的双层有序构型的 BL M膜中的 C6 0 是一种良好的、具有电荷传输能力和光敏特性的新型传感材料
In this paper, the C6 0 modified solid support bilayer membrane (s-BL M) was studied by calculating the dielectric constant ε and compared with the unmodified s-BL M. Studies have shown that the permittivity of C5-modified s-BL M ε = 5.1 (up to 5.5 under photoexcitation conditions) is much larger than that of unmodified s-BL M (ε = 2). 4), even exceeding the dielectric constant of the C6 0 solid. At this point, the detection sensitivity of C6 0 -modified s-BL M to I- increased by about 2 orders of magnitude. And its mechanism was analyzed. The analysis shows that C6 0 in a bilayer ordered BLM film with a supramolecular structure is a good new sensing material with charge transport capability and photosensitivity
