利用LB技术制备纳米有序螺吡喃类化合物光信息储存超分子膜,着重研究了螺吡喃类化合物在不同亚相和pH值时的成膜条件和结构之间的关系,并对膜的稳定性,光致变色特性和抗疲劳能力做了较详细的研究。得到一种粒度均匀,分辨率在微米量级的超分子膜,并提出了作为三维贮储光记忆材料时一种写入和非破坏性读出的方法。
The LB information was used to prepare nanostructured spiropyran optical information storage supramolecular films. The relationship between the film formation conditions and structure of spiropyran compounds at different subphase and pH was studied emphatically. Stability, photochromic properties and fatigue resistance made a more detailed study. A super-molecular film with a uniform particle size and a resolution in the micrometer range was obtained, and a write-in and non-destructive readout method was proposed as a three-dimensional storage optical memory material.
