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.

该奖项得到了主要的研究工具和化学研究工具计划的支持。来自佛罗里达州立大学的Mykhailo Shatruk教授和同事Igor Alabugin，Susan Latturner，Biwu Man和James Frederich获得了微型对焦，双源单晶体衍射仪。通常，X射线衍射仪可以准确，精确地测量分子的完整三维结构，包括键距离和角度，并提供有关分子相对于相邻分子的空间排列的准确信息。这里描述的研究影响了许多领域，包括有机和无机化学，材料化学和生物化学。该工具是该机构化学和生物化学研究生和本科生的教学和研究培训的组成部分。学生参与化学和蛋白质研究。该资源也由相邻的本科机构利用。该提案旨在增强各级研究和教育。它对于研究基于分子的材料的温度和光诱导的自旋态切换特别有用，可用于鉴定使用熔融金属通量制备的化合物。衍射仪还用于研究卤化物钙钛矿的磷光分子，用于能量应用，以及用富含碳富含碳的分子和纳米材料制成的结构表征的超分子物种。它也用于表征用于评估蛋白质 - 蛋白质相互作用调节器的合成天然产品。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
