摘要: 早在1978年,光致变色研究的先驱者Heller教授就提出光致变色反应可用于光信息存储和光记录材料,十年之后诺贝尔化学奖获得者Lehn教授又提出了光子器件,光致变色分子和体系的设计与合成为研制不同种类的光子器件提供了物质基础和可能性[1].具有光致变色特性的有序分子膜的制备及光学物理性质研究更吸引着众多的科学家进入这一研究领域[2~4].

Abstract: An azobenzene amphiphile bearing perfluoro alkane chain (n-PFHAZO) was synthesized. L-B films with layer order periodic structure were fabricated. The n-PFHAZO molecules in the L-B films exhibited an excellent cis-trans photoisomerization and thermoisomerization. The process is completely reversible. May be the perfluoro alkane chains afford adequate free volume for the isomerization in L-B films.
