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.

凭借化学研究仪器和设施（CRIF）计划的这一奖项，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。这一设备将加强若干领域的研究，包括：a）分子基材料的小角和广角X射线散射，例如，酞菁的刚性双层厚度膜; B）用于在分离各种金属离子中的高选择性的金属离子印迹聚合物（MIP）的表征; c）光响应液晶; d）来自金属化或矿化的聚合脂质相的纳米复合材料; e）蛋白质膜组件中的结构和功能; f）用于表面光谱学和化学传感的层压平面波导; g）由六核金属簇合物支撑的树枝状聚合物;和h）金属簇支撑的多孔固体。X射线衍射仪允许精确和精确测量分子的全部三维结构，包括键距和键角，并且它提供了关于分子相对于相邻分子的空间排列的精确信息。
