Morphology changes of a hybrid composed of photo-responsive molecule and inorganic layered compound have been successfully induced by photo-irradiation. In this study, a key nanostructure of the layered hybrid, which reversibly induce a nanosheet sliding and interlayer distance changes by photochemical reaction, have been analyzed by X-ray diffraction measurement, UV-Vis and IR absorption spectroscopy and thermogravimetric analysis.We have found that a nanosheet sliding in the hybrid has been efficiently induced by coupling photochemical reaction of molecules with the unique nanostructure of molecular assembly, which is constructed in the interlayer spaces of inorganic layered structure. It is considered that the interaction between molecular assembly and inorganic nanosheets as a microenvironment is very important for inducing a large morphology change such as a nanosheet sliding.

光响应分子与无机层状化合物的杂化材料在光照射下发生了形貌变化。本研究通过X射线衍射、紫外-可见和红外吸收光谱以及热重分析等手段，对层状杂化材料中的一个关键纳米结构进行了分析，发现通过分子组装的独特纳米结构与分子的光化学反应的耦合，可以有效地诱导纳米片的滑动，其构建在无机层状结构的层间空间中。据认为，分子组装体和无机纳米片之间的相互作用作为一个微环境是非常重要的诱导大的形态变化，如纳米片滑动。
