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.

Single chain bolaamphiphile containing cinnamyl moiety [4-(ω-hydroxydecanyloxy) (ω-hydroxydecanyl)cinnamate, abr. HDC] was designed and synthesized. The photodimerization of the HDC molecules induced by UV light was the first time realized in organic solutions. The dimerized HDC was separated and formed spherical vesicles in 20% ethanol/water mixed solvents. The solvents' dielectric constants were found to play an important role in the photodimerization process. Both the occurrence of the photodimerization reaction and the rate of the reaction were affected by the dielectric constant value of the solvents.
