Purchase of an X-ray Diffractometer Equipped with a CCD-Detector

在化学研究仪器和设施（CRIF）计划的支持下，宾夕法尼亚大学化学系将获得一台带有CCD探测器的x射线衍射仪，用于小分子衍射。该设备将加强若干领域的研究，包括：a)金属硼酰和等电子金属杂原子硼酰配合物的合成及其化学和生物活性特性；B)通过金属和原子转移机制控制烯烃自由基聚合；C)有机硅和锗化合物的过渡金属配合物：新结构和催化剂；D)基于共轭卟啉的仿生能量传导和催化组件；e)催化剂结构和功能的阐明。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。这些研究将在许多领域产生影响，包括制备更有效的催化剂、材料化学和生物技术。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Pennsylvania will acquire a X-ray diffractometer with CCD detector for small molecule diffractometry. This equipment will enhance research in a number of areas including the following: a) synthesis and chemical and bioactivity properties of metallatricarbaboranyl and isoelectronic metallaheteroatomboranyl complexes; b) control of radical polymerization of olefins by metalloradical and atom transfer mechanisms; c) transition metal complexes of organosilicon and -germanium compounds: new structures and catalysts; d) conjugated porphyrin-based assemblies for biomimetic energy transduction and catalysis; and e)elucidation of catalyst structure and function.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. These studies will have an impact in a number of areas, including the preparation of more efficient catalysts, materials chemistry and biotechnology.
