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.

The synthesis of a novel α phosphorus containing spin trap, DEPDMPO(5 diethoxy Phosphoryl 2, 5 dimethyl 1 pyrroline \%N\% oxide) and the evaluation of its ability to spin trap the hydroxyl and the superoxide anion radicals were described in the present article. The ability to trap an active superoxide anion radical generated in the photo system Ⅱ(PSII) and the stability of their spin adduct of DEPDMPO as well as three previously reported traps DMPO, DEPMPO and M 3PO were comparatively analyzed according to their chemical structures. In addition, the effects of 2 methyl and \%α\% phosphoryl substituted analogues of DMPO on the stabilities of the corresponding spin adduts were systematically
