研究了胆甾液晶二氮杂冠醚Ｎ，Ｎ－双［胆甾－５－烯－３β－氧羰甲基］－１，１０－二氮－４，７，１３，１６－四氧环十八烷（１）及其与Ｅｕ３＋的配合物（２）、２与苯甲酸的混配物（３）的ＬＢ膜和荧光性质．结果表明：１、２和３都在水溶液亚相液面形成稳定的单分子膜，但只有１的单分子面积受亚相ｐＨ的影响．１、２和３的单分子膜都容易转移到石英基片上形成ＬＢ膜，其中２和３为Ｘ型，转移比分别为０．６和１．０．在ＬＢ膜中，在２的荧光激发波长范围比在溶液中的宽，荧光强度也比在溶液中的强得多．在２中添加苯甲酸形成３可改善ＬＢ膜中分子有序排列，荧光强度增强到无苯甲酸时的２．０倍．所有这些ＬＢ膜，即使添加了苯甲酸的，都不是很稳定．
Cholesteric liquid crystal aza-crown ether N, N’-bis [cholest-5-ene-3β-oxycarbonylmethyl] -1,10-diazide-4,7,13,16-tetraoxy LB film and fluorescence properties of octadecane (1) and its complex with Eu3 + (2), mixture of 2 and benzoic acid (3). The results showed that: 1, 2 and 3 all formed stable monolayer in the aqueous solution subfacies, but only 1 molecule area was affected by the pH of the subphase. Monolayers of 1, 2, and 3 were easily transferred to the quartz substrate to form LB films, where 2 and 3 were X-type and the transfer ratios were 0.6 and 1.0, respectively. In the LB film, the fluorescence excitation wavelength range at 2 is wider than in solution, and the fluorescence intensity is also much stronger than in solution. The addition of benzoic acid to form 3 in 2 can improve the ordered arrangement of the molecules in the LB film, and the fluorescence intensity increases to 2.0 times that of benzoic acid. All of these LB films, even with the addition of benzoic acid, are not very stable.
