This Research award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professors Robert D. Pike at the College of William and Mary and Craig A. Bayse at Old Dominion University to carry out structural, reactivity and computational studies on metal-organic networks which can act as luminescence detectors and chemical catalysts. Metal-organic networks are large molecules in which metal atoms (e.g. copper) are linked together to form long-range lattices, which may be one- two- or three-dimensional in structure. The metals in these materials have the ability to bind small molecules, including gases. In the case of copper in the +1 oxidation state, this binding changes the fluorescence color emitted by the copper ions. As a result, metal-organic networks containing copper can potentially act as sniffing devices for environmental chemicals. In addition, this same type of molecular binding may enable efficient and environmentally benign catalytic reactions of small molecules to be carried out using flow-through reactors charged with metal-organic network catalysts. The research is being conducted entirely by undergraduate chemistry students. These students, who are being trained at the interface of chemistry, materials science and photophysics, are part of the next generation of U.S. scientists and will serve as teachers for the Crystals program, aimed at enhancing interest in the sciences at the elementary school level. The Crystals program utilizes hands-on experiments to demonstrate for fifth grade students how the physical properties and mathematical symmetry of beautiful crystals reflect the underlying chemical structure. The research is ultimately intended to produce better detectors for chemical pollutants and/or weapons agents and to give rise to more environmentally-friendly catalysts for chemical synthesis.

这项研究奖在无机，生物无机和有机化学计划支持教授罗伯特D。派克在威廉和玛丽学院和克雷格A。Bayse在Old自治领大学进行结构，反应性和计算研究的金属有机网络，可以作为发光检测器和化学催化剂。金属有机网络是其中金属原子（例如铜）连接在一起以形成长程晶格的大分子，其在结构上可以是一维、二维或三维的。这些材料中的金属具有结合小分子的能力，包括气体。在铜处于+1氧化态的情况下，这种结合改变了铜离子发射的荧光颜色。因此，含有铜的金属有机网络可能作为环境化学品的嗅探装置。此外，这种相同类型的分子结合可以使得能够使用装有金属-有机网络催化剂的流通式反应器进行小分子的有效和环境友好的催化反应。这项研究完全由本科化学专业的学生进行。这些学生正在接受化学，材料科学和物理学的接口培训，是下一代美国科学家的一部分，并将担任晶体计划的教师，旨在提高小学阶段对科学的兴趣。晶体计划利用动手实验来演示五年级学生如何美丽的晶体的物理性质和数学对称性反映了潜在的化学结构。这项研究的最终目的是生产更好的化学污染物和/或武器制剂检测器，并为化学合成提供更环保的催化剂。
