基于多孔金属有机骨架（MOFs）的有序薄膜的制备是未来功能纳米材料的实际应用之一。在这里，我们报告的创建一个高度定向的三维（3-D）多孔柱层型MOP薄膜的金属基板上使用一步一步的方法基于液相外延。同步加速器X射线衍射（XRD）研究清楚地表明，薄膜是结晶的，并且其取向在相对于衬底的水平和垂直方向上都受到高度控制。这份报告提供了第一次确认的细节，不仅结晶度，但也取向的3-D MOF薄膜使用同步辐射XRD。此外，我们还证明了它的客体吸附/脱附行为，通过使用原位XRD测量。这里提出的结果将承诺在未来的MOF为基础的纳米器件的制造有用的见解。
Fabrication of a crystalline ordered thin film based on the porous metal organic frameworks (MOFs) is one of the practical applications of the future functional nanomaterials. Here, we report the creation of a highly oriented three-dimensional (3-D) porous pillared-layer-type MOP thin film on a metal substrate using a step-by-step approach based on liquid-phase epitaxy. Synchrotron X-ray diffraction (XRD) study clearly indicates that the thin film is crystalline and its orientation is highly controlled in both horizontal and vertical directions relative to the substrate. This report provides the first confirmation of details of not only the crystallinity but also the orientation of 3-D MOF thin film using synchrotron XRD. Moreover, we also demonstrate its guest adsorption/desorption behavior by using in situ XRD measurements. The results presented here would promise useful insights for fabrication of MOF-based nanodevices in the future.
