CRIF:MU Purchase of an X-ray Diffractometer for Research and Education

凭借化学研究仪器和设施：多用户计划（CRIF：MU）的这一奖项，加州理工学院化学与化学工程系将获得一台带有低温晶体冷却系统（LT）的X射线衍射仪（CCD）。它将用于研究项目，包括1）用于烯烃聚合，燃料生产和增值化学品的有机金属催化剂的合成，2）沸石的机理研究，3）蛋白质折叠以及蛋白质的氧化还原性质和分子线电子转移的机理研究，4）用于太阳能电池开发的咔咯化合物的开发，5）用于生物传感器开发的复杂大环的开发，6）复分解催化剂的开发，7）天然系统中金属中心的催化过程的机理研究，和8）复杂和生物相关有机化合物的“引导”合成。新的X射线衍射仪将被安置在加州理工学院贝克曼研究所化学与化学工程系的X射线晶体学实验室。单晶X射线晶体学技术可以准确和精确地确定分子的完整三维结构，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。这些研究将在许多领域产生影响，特别是合成化学。

With this award from the Chemistry Research Instrumentation and Facilities: Multi User program (CRIF:MU), the Department of Chemistry and Chemical Engineering at California Institute of Technology will acquire an X-ray diffractometer (CCD) with a low-temperature crystal cooling system (LT). It will be utilized in research projects including 1) synthesis of organometallic catalysts for olefin polymerization, fuel production, and value-added chemicals, 2) mechanistic studies of zeolites, 3) mechanistic studies of protein folding as well as redox properties and molecular wire electron transfer of proteins, 4) development of corrole compounds for solar cell development, 5) development of complex macrocycles for biosensor development, 6) development of metathesis catalysts, 7) mechanistic studies of the catalytic processes of metallic centers in natural systems, and 8) "guided" synthesis of complex and biologically relevant organic compounds. The new X-ray diffractometer will be housed in the X-ray Crystallography Lab of the Division of Chemistry and Chemical Engineering in the Beckman Institute at the California Institute of Technology.The technique of single-crystal X-ray crystallography allows accurate and precise determination 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, especially synthetic chemistry.
