Upgrade of NMR Facilities for Research and Teaching

该奖项由2009年美国复苏和再投资法案(公法111-5)资助。在化学研究仪器和设施：多用户计划(CRIF：MU)的支持下，德克萨斯大学阿灵顿分校(UTA)化学系将升级一台500 MHz核磁共振(核磁共振)光谱仪，配备新的控制台和宽带探头，并获得两个样品旋转木马(用于300 MHz和500 MHz光谱仪)。该仪器支持的研究活动涉及合成有机、无机、物理有机和聚合物化学等领域。这些研究包括：(I)用于捕光的多金属络合物，(Ii)具有特殊催化和发光性能的新型含氟聚(吡唑基)硼酸盐配体的金属络合物，(Iii)具有增强导电性、可能的超导电性以及电致和光致发光性能的聚合物材料，(Iv)生物活性生物碱的全合成，(V)新型有机催化剂的开发，以及(Vi)合成方法的开发。核磁共振波谱是现代化学研究中必不可少的有力工具。核磁共振谱使研究人员能够研究分子如何反应，并识别反应产物和不稳定的反应中间体。关于原子如何在所研究的分子中连接的结构信息是通过观察原子的核磁自旋性质引起的能级之间的跃迁而获得的。这些仪器将用于支持UTA本科生、研究生和博士后的研究项目，并培训他们使用最先进的仪器。UTA将与塔兰特县学院一起试行一项计划，允许二年级有机实验室的学生获得并解释他们实验的数据。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With support from the Chemistry Research Instrumentation and Facilities:Multiuser program (CRIF:MU), the Department of Chemistry at the University of Texas at Arlington (UTA) will upgrade a 500 MHz nuclear magnetic resonance (NMR) spectrometer with a new console and broadband probe and obtain two sample carousels (for a 300 MHz and the 500 MHz spectrometer). The research activity to be supported by this instrument spans areas in synthetic organic, inorganic, physical organic, and polymer chemistry. These include the study of (i) multi-metal complexes for light harvesting, (ii) metal complexes of new fluorinated poly(pyrazolyl)borate ligands with unusual catalytic and luminescent properties, (iii) polymeric materials with enhanced electrical conductivity, possible superconductivity, and electro- and photo luminescent properties, (iv) the total synthesis of bioactive alkaloids, (v) the development of new organocatalysts, and (vi) synthetic methods development. NMR spectroscopy is a powerful tool essential for progress in modern chemical research. NMR spectra enable researchers to study how molecules react and to identify reaction products and unstable reaction intermediates. Structural information on how the atoms are connected in the molecules under study is obtained from observing transitions between energy levels arising from the nuclear magnetic spin properties of atoms. The instruments will be used to support research projects of undergraduate, graduate and postdoctoral students at UTA and train them in the use of state-of-the-art instrumentation. UTA will pilot a program with Tarrant County College to allow students in a sophomore organic lab to obtain and interpret data from their experiments.
