This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. The State University of New York - Buffalo is acquiring a diffractometer with a high brilliance microfocus Cu source and a hybrid photon counting detector to support the research of Professor Jason Benedict and colleagues Timothy Cook, David Lacy, Janet Morrow, and Mark Swihart. 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, catalysis, and materials chemistry. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution. The reach of the instrumentation will include existing research and teaching programs at UB and some collaborative efforts with nearby institutions (D’Youville College, Saint Bonaventure University, and Buffalo State College).The award is aimed at enhancing research and education at all levels. Research enabled by the instrument is focused on the study and characterization of a wide variety of substances including photoactive crystalline materials especially in metal organic frameworks (MOFs) and in pharmaceutical co-crystals, determining the structure of self-assembled co-facial porphyrin catalysts and photoactive metallocages, characterization of new MOFs containing antibiotic linkers and high entropy metal oxides prepared by flame-based aerosol reactors. Researchers will also explore the structures of paramagnetic transition metal complexes used as magnetic resonance imaging (MRI) probes, the structures of air sensitive organometallic catalysts, especially Mn and Ru complexes.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.

该奖项由主要研究仪器项目和化学研究仪器项目共同支持。纽约州立大学布法罗分校正在购买一台具有高亮度微聚焦铜源的衍射仪和一个混合光子计数探测器，以支持Jason Benedict教授及其同事Timothy Cook、David Lacy、Janet Morrow和Mark Swihart的研究。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、催化和材料化学。该仪器是该机构化学和生物化学专业本科生和研究生教学、科研和培训不可或缺的一部分。该仪器的覆盖范围将包括亚利桑那州立大学现有的研究和教学项目，以及与附近机构(D‘Youville学院、圣博纳文迪大学和布法罗州立学院)的一些合作努力。该奖项旨在加强所有级别的研究和教育。该仪器的研究重点是各种物质的研究和表征，包括光活性晶体材料，特别是金属有机骨架(MOF)和药物共晶体中的光活性晶体材料，确定自组装的共面卟啉催化剂和光活性金属分配的结构，包含抗生素连接物和由火焰气溶胶反应器制备的高熵金属氧化物的新MOF的表征。研究人员还将探索用作磁共振成像(MRI)探针的顺磁性过渡金属络合物的结构，空气敏感的有机金属催化剂的结构，特别是锰和Ru络合物。这一奖项反映了NSF的法定使命，并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。
