Upgrade of UNC Chemistry X-ray Single Crystal Diffraction Facility

在化学研究仪器和设施：部门多用户仪器（CRIF：MU）计划的支持下，位于查佩尔山的北卡罗来纳州大学化学系（UNC-CH）将获得一台带有CCD检测器和低温系统的X射线衍射仪。该仪器将支持各种各样的研究项目，包括：新材料和工艺的超分子方法;金属催化聚合;金属介导的有机转化;以及用于阳离子烯烃环化，对映选择性多米诺反应和天然产物合成的新催化剂。该仪器将被化学系以及环境科学和药学院等其他项目的大量用户使用。同样，该仪器将影响来自UNC-CH许多学科的研究生和博士后研究员的研究培训。X射线衍射仪可以准确和精确地测量分子的完整三维结构，包括键距和角度，并提供有关分子相对于相邻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，特别是重要的有机和无机化学品以及聚合物材料的合成。

With support from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation (CRIF:MU) Program, the Department of Chemistry at the University of North Carolina at Chapel Hill (UNC-CH) will acquire an X-ray diffractometer with CCD detector and low-temperature system. This instrument will support a large variety of research projects, including: supramolecular approaches to novel materials and processes; metal-catalyzed polymerization; metal-mediated organic transformations; and new catalysts for the cation-olefin cyclization, enantioselective domino reactions, and natural product synthesis. The instrument will be used by a large number of users in the Chemistry Department as well as other programs such as Environmental Sciences and the School of Pharmacy. Similarly, the instrument will impact the research training of graduate students and postdoctoral fellows from many disciplines at UNC-CH.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 neighboring molecules. These studies will have an impact in a number of areas, especially synthesis of important organic and inorganic chemicals and polymeric materials.
