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.

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使用用于小分子衍射测定法的CCD检测器获得X射线衍射仪。该设备将在许多领域的研究中增强以下各个领域的研究：a）金属核果核果和等纤维质量金属甲酰胺原木氨基烷基综合体的合成以及化学和生物活性特性； b）通过金银和原子转移机制控制烯烃的自由基聚合； c）有机硅和 - 藻类化合物的过渡金属复合物：新结构和催化剂； d）基于卟啉的共轭组件，用于仿生能量转导和催化； X射线衍射仪可以准确，精确地测量分子的整个三维结构，包括键距离和角度，并且提供了有关分子相对于相邻分子的空间布置的准确信息。 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。
