Mechanism of photomechanical function on photo-responsive layered hybrid

光响应分子与无机层状化合物组成的杂化物在光照射下成功地发生了形态变化。本研究通过x射线衍射测量、紫外-可见和红外吸收光谱以及热重分析分析了层状杂化物的关键纳米结构，该结构通过光化学反应可逆地诱导纳米片滑动和层间距离变化。我们发现，在无机层状结构的层间空间中，分子的光化学反应与分子组装的独特纳米结构的耦合有效地诱导了纳米片在杂化材料中的滑动。分子组装与无机纳米片之间的相互作用作为微环境对于诱导纳米片滑动等大的形态变化是非常重要的。

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.
