有机染料-层状硅酸盐光活性纳米复合材料

有机-无机纳米复合材料，尤其是有机客体插层入无机层状固体自组装形成的纳米复合材料，因其独特的微观结构与性能，在超分子构筑纳米材料领域中具有特殊地位。本文主要介绍了光致变色与光致发光光功能性有机染料插层层状硅酸盐纳米复合材料的研究进展，着重讨论了螺吡喃、偶氮、二芳基乙烯、芘、香豆素等染料在二维纳米片层间独特的光学行为、有序排列形态、构筑的多层功能性薄膜及其在光功能性材料开发方面的应用前景。

Organic Dye-Layered Silicate Optical Functional Nanocomposites

Organo inorganic nanocomposites, particularly the self organized nanocomposites produced by the intercalation of the organic dye guests into the inorganic layered solids, due to their special microstructure and properties, have occupied important place in the field of nanocomposites. In this paper, recent developments in the study of the intercalation of photochromic and photoluminescent dyes, including spiropyran,azobenzene, diarylethenes, coumarine and pyrene, into layered silicates are reviewed. The focus is on the special optical behavior and the highly ordered microstructure of the dyes in the two dimensional layers of silicates. Their applications in optical functional materials are also discussed.
