| 摘 要： | 合成了一种含有偶氮基团的两亲性萘酚衍生物。该化合物在纯水亚相上能够形成稳定的单分子膜 ,并可转移到固体载体上形成LB膜。在LB膜中观测到酸致变色现象 ,即置于HCl气氛中的有序分子薄膜由黄色转变成紫色 ,而用NH3 气体处理该LB膜后 ,膜的颜色可以恢复如初。这一过程可以反复多次。

| Abstract: | An amphiphilic azo-containing naphthol derivative, 4-(4′-hexadecyloxy phenylazo)-1-naphthol (C16AzoNp) was synthesized. It is found that C16AzoNp can form a stable monolayer on water surface. The monolayer can be transferred onto solid substrates to form LB films. Acidichromism was observed in the deposited LB film, i.e. the film turned its color from yellow to purple upon exposing to HCl gas and the color could be returned to its original upon exposing to NH 3 gas. This reversible color change could be... |
