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).第一次观察到该分子在有机溶剂中经紫外光照发生光致二聚.分离出来的二聚HDC在20%的乙醇/水混合溶剂中能形成球形的囊泡.同时发现溶剂的介电常数大小与光致二聚过程密切相关,介电常数的大小不仅关系到反应发生与否,而且直接影响到反应的速率.
A bola-type amphiphilic molecule HDC (4- (10-hydroxydecyloxy) -10-hydroxydecyloxy cinnamate) containing cinnamic acid groups was prepared for the first time in the presence of an organic solvent The dimerized HDC isolated from dimerized HDC can form spherical vesicles in 20% ethanol / water mixed solvent.It is also found that the dielectric constant of solvent is closely related to the photodimerization process, The size of the electric constant is not only related to the reaction occurs, but also directly affects the reaction rate.
