采用LB技术制备了螺吡喃类化合物纳米簇组装体，系统研究了面相、pH值、制备条件与制备的LB膜结构之间的关系。还详细研究了螺吡喃LB薄膜的稳定性和光致变色疲劳特性，这些特性在光信号存储应用中至关重要。获得了一种具有相似粒径的均匀分布的J聚集体的超分子薄膜，光学分辨率达到微米量级。最后，提出了一种将这种LB膜用作光信号存储膜的无损读出方法。
Nanocluster assemblies of spiropyran compounds have been prepared by means of LB technique, and the relations between the subphase, pH value, condition of preparation and the structure of the fabricated LB film are systematically investigated. The stability, photochromic fatigue properties of the spiropyran LB film, which are of primary importance in optic signal storage applications, are also studied in detail. A kind of supermolecular film with homogeneously distributed J aggregates of similar granular size has been obtained with the optical resolution in the order of micrometer. Finally, a nondestructive readout method for such an LB film to be used as the optic signal storage film is proposed.
