| 摘 要： | 本文合成了10,12-双炔廿三酸,并用其在Si、SiO_2、CaF_2等基片上沉积了LB膜,结果表明,10,12-双炔廿三酸的镉盐成膜更稳定。这种LB膜在紫外光辐照下很快聚合,聚合前后的紫外-可见吸收光谱发生规律性的变化,并保持层状结构,等同周期稍变。通过红外吸收的二向色性分析,确定了该分子的取向。

| Abstract: | 10,12-Tricosadiynoic acid was synthesized and its LB film was deposited onto quartz, CaF2 and silicon substrates. The polymerization behaviour of LB film of 10,12-tricosadiynoic acid under UV-radiation was monitored. The molecular orientation of the 10,12-tricosadiynoic acid Cd2+ salt LB film was analyzed by linear dichroic behaviour of FTIR spectrometry. The results of small angle X-ray diffraction showed that the layer structure of LB film was not destroyed after polymerization, and the equal period, 4. 26 nm, has slightly changed, but the line intensity of X-ray diffraction decreased. |
