氢键诱导液晶化合物的变温红外光谱研究

Temperature--dependent FTIR Spectra on a intermolecular Hydrogen Bonded Liquid Crystal

通过变温红外光谱研究了存在于４－［４－（２－氯－３－甲基丁酰氧基）－苯乙烯基］吡啶（ＭＢＳＢ）和对庚氧基苯甲酸（７ＢＡ）间的分子间氢键的稳定性及该氢键复合物的酯羰基基因与温度的依赖关系．结果表明，ＭＢＳＢ与７ＢＡ间的分子间氢键在液晶的清亮点以下具有良好的热稳定性．

The stability of intermolecular hydrogen bonding between 4-(2-chloro-3--methyl butanoyloxy)--4'-stilbazole (MBSB) and 4-heptanoxyl-benzoic acid (7BA) was investigated by means of temperature dependent FTIR spectra, meanwhile the relationship between the ester carbonyl group andtemperature was also studied. The results show that the intermolecular hydrogen bonding is stable below the liquid crystal to isotropic transition temperature.
