摘要
用表面压－面积等温线，原子力显微镜（ＡＦＭ）和Ｘ射线衍射（ＸＲＤ）对两种具有不同取代位置的新型双 头基两亲分子（ｂｏｌａａｍｐｈｉｐｈｉｌｅ）从Ａ和Ｂ在气液界面形成的Ｌａｎｇｍｕｉｒ铺展膜的结构进行了研究，化合物１，２０－二 十碳二β－萘酯（Ｂ）在气液界面形成了拉伸型Ｌａｎｇｍｕｉｒ单分子膜，而化合物 １，２０－二十碳 α－萘酯（Ａ）在气液 界面则形成了具有三层分子厚度的二维结晶膜.
Bolaamphiphile, in which two head groups are linked by one or two hydrophobic chains, has been attracting much interest in recent years. The structures of the Langmuir films spread from two novel bolaam- phiphiles containing α-naphthyl and β-naphthyl groups at the air/water interface have been investigated. Surface pressure -area isotherms, AFM and XRD measurements reveal that when spreading at the air/water surface, the molecule containing α-naphthyl forms a triple-layer Langmuir film, while the one containing β-naphthyl forms a stretched monolayer.
