对短正构烷烃（C6H14）多层膜在正构烷烃硫代酸酯（C6H13S）单层上的分子取向进行了C - k边近边x射线吸收精细结构研究。我们发现，正构烷烃多层膜的分子取向与形成多层膜的正构烷烃硫化物单层膜的分子取向一致。噻吩的单层结构对正构烷烃层的排列也有显著的影响。从表面和界面自由能的能量平衡角度讨论了正构烷烃膜的生长方式。
C K-edge near-edge X-ray absorption fine structure studies have been performed on the molecular orientation of short n-alkane (C6H14) multilayers on n-alkanethiolate (C6H13S) monolayers. We have found that the molecular orientation of the n-alkane multilayers is in accordance with that of n-alkanethiolate monolayers on which the multilayers were formed. Monolayers of thiophene also have a significant effect on the alignment of the n-alkane multilayers condensed on the monolayers. The growth manner of the n-alkane films is discussed in terms of the energy balance between surface and interface free energies.
