Acquisition of a Powder and Thin Film X-Ray Diffractometer System

根据化学研究仪器和设施（CRIF）项目的奖励，亚利桑那大学化学系将获得粉末和薄膜x射线衍射仪系统。该设备将加强在以下几个领域的研究：a)分子基材料的小角度和广角x射线散射，例如酞菁的刚性双层厚度薄膜；b)表征金属离子印迹聚合物（MIPs）在各种金属离子分离中的高选择性；C)光响应液晶；D)由金属化或矿化聚合脂相组成的纳米复合材料；E)蛋白质膜组件的结构和功能；F)用于表面光谱和化学传感的层状平面波导；G)六核金属团簇支撑的枝状大分子；h)金属团簇支撑多孔固体。x射线衍射仪可以精确测量分子的完整三维结构，包括键的距离和角度，并提供分子相对于邻近分子的空间排列的准确信息。

With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Arizona will acquire a powder and thin film X-ray diffractometer system. This equipment will enhance research in a number of areas including the following: a) small angle and wide angle X-ray scattering of molecule-based materials, e.g., rigid bilayer thickness films of phthalocyanines; b) characterization of metal ion imprinted polymers (MIPs) for high selectivities in separation of various metal ions; c) photoresponsive liquid crystals; d) nanocomposites from metallized or mineralized polymerized lipid phases; e) structure and function in protein film assemblies; f) laminate planar waveguides for surface spectroscopy and chemical sensing; g) dendrimers supported by hexanuclear metal clustsers; and h) metal cluster-supported porous solids.The X-ray diffractometer allows accurate and precise measurements of the full three dimensional structure of a molecule, including bond distances and angles, and it provides accurate information about the spatial arrangement of the molecule relative to the neighboring molecules.
