MRI: Acquisition of a Dual-Source Single-Crystal X-ray Diffractometer

该奖项由主要研究仪器项目和化学研究仪器项目支持。佛罗里达州立大学的Mykhailo Shatruk教授和他的同事伊戈尔·阿拉布金、苏珊·拉特纳、比武·曼和詹姆斯·弗雷德里奇获得了一台微焦点、双源单晶衍射仪。通常，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，包括键距离和角度，并提供关于分子相对于邻近分子的空间排列的准确信息。这里描述的研究影响到许多领域，包括有机化学和无机化学、材料化学和生物化学。该仪器是该机构化学和生物化学专业的研究生和本科生的教学、研究和研究培训的组成部分。学生们从事化学和蛋白质研究。邻近的本科院校也利用了这一资源。该提案旨在加强各级的研究和教育。这对于研究分子基材料中温度和光诱导的自旋态转换特别有用，对于识别使用熔融金属助熔剂制备的化合物特别有用。衍射仪还被用于研究用于能源应用的卤化物钙钛矿中的磷光分子，以及用于表征由扭曲的富碳分子和纳米材料制成的超分子物种的结构。这一奖项反映了NSF的法定使命，通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. Professor Mykhailo Shatruk from Florida State University and colleagues Igor Alabugin, Susan Latturner, Biwu Man and James Frederich have acquired a microfocus, dual source single crystal diffractometer. In general, an X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The studies described here impact many areas, including organic and inorganic chemistry, materials chemistry and biochemistry. This instrument is an integral part of teaching as well as research and research training of graduate and undergraduate students in chemistry and biochemistry at this institution. Students are involved in chemical and protein research. The resource is also utilized by neighboring primarily undergraduate institutions. The proposal is aimed at enhancing research and education at all levels. It is especially useful for studying temperature-, and light-induced spin-state switching in molecule-based materials, for the identification of compounds prepared using molten metal fluxes. The diffractometer is also being used in investigations of phosphorescent molecules from halide perovskites for energy applications, and for structurally characterizing supramolecular species made from contorted carbon-rich molecules and nanomaterials. It is also employed for the characterization of synthesized natural products used to evaluate protein-protein interaction modulators.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
