With this award from the Major Research Instrumentation Program (MRI) that is co-funded by the Chemistry Research Instrumentation Program (CRIF), Professor Mihaela Iovu from University of Texas Dallas and colleagues A. Dean Sherry, John Ferraris, Dennis Smith and Jung-Mo Ahn will acquire a 500 MHz NMR spectrometer equipped with two probes. The proposal is aimed at enhancing research training and education at all levels, especially in areas such as (a) polythiophene-CdSe blends for bulk heterojunction solar cells, (b) perfluorocyclobutyl (PFCB) polymers for proton exchange membrane (PEM) fuel cells and gas separation applications, (c) fluorovinylene aryl ether telechelic polymers for thermal chain extension and tandem crosslinking, (d) lanthanide complexes and polymers as metabolic sensors for Magnetic Resonance Imaging, and (e) development of peptidomimetics for treatment of diabetes mellitus.Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic/inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research.

来自德克萨斯大学达拉斯分校的Mihaela Iovu教授及其同事A.迪安·雪莉、约翰·费拉里斯、丹尼斯·史密斯和郑莫·安将获得一台配备两个探头的500 MHz核磁共振光谱仪。该提案旨在加强各级的研究培训和教育，特别是在以下领域：（a）用于本体异质结太阳能电池的聚噻吩-CdSe共混物，（B）用于质子交换膜燃料电池和气体分离应用的全氟环丁基（PFCB）聚合物，（c）用于热扩链和串联交联的氟乙烯基芳基醚遥爪聚合物，（d）镧系元素络合物和聚合物作为磁共振成像的代谢传感器，以及（e）开发用于治疗糖尿病的肽模拟物核磁共振（NMR）光谱是化学家可用于阐明分子结构的最有力的工具之一。它用于识别未知物质，表征分子内原子的特定排列，并研究溶液中分子之间相互作用的动力学。对于从事前沿研究的化学家来说，使用最先进的NMR光谱仪是必不可少的。这些NMR研究的结果将对合成有机/无机化学、材料化学和生物化学产生影响。该仪器将成为教学和研究的一个组成部分。
