制备了一种含肉桂酸基团的Bola型两亲分子HDC(4-(10-羟基癸氧基)-10-羟基癸氧基肉桂酸酯).该分子在空气/水界面形成多分子层Langm uir膜结构.紫外光照可使膜中H D C 分子发生光致二聚,也可使H D C与1,16-十六碳二醇形成的混和膜中HDC 分子发生二聚.光照前后膜中分子倾角分别为58.8°和53.2°.从实验结果推测了分子排列模型,认为HDC 分子在LB膜中有序排列,这来源于分子间π-π相互作用和疏水亚甲基链的Z 型构象堆积.
A bola-type amphiphilic molecule HDC (4- (10-hydroxydecyloxy) -10-hydroxydecyloxy cinnamate) containing a cinnamic acid group was prepared which forms a multi-molecular layer at the air / water interface Langmuir membrane structure.Ultraviolet light can cause HDC molecules in the membrane photodimerization, HDC molecules can also HDC and 1,16-hexadecanediol mixed membrane formed dimerization before and after the film molecular tilt angle 58.8 ° and 53.2 °, respectively.The molecular arrangement model was deduced from the experimental results, and it is considered that the HDC molecules are arranged in the LB film in an ordered manner due to the intermolecular π-π interaction and the Z-type conformational packing of the hydrophobic methylene chains.
