摘要: 本文合成了10,12-双炔廿三酸,并用其在Si、SiO2、CaF2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 LBfilm was deposited onto quartz, CaF2and silicon substrates. The polymerization behaviour of LBfilm 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 FTIRspectrometry. 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.

Key words: 10,12-tricosadiynoic acid, Light-polymerized LB film, Equal period of LES film, Analysis of linear dichroism spectra
