CAREER: Synthesis Of Multifunctional Hybrids Of Reduced Rhenates and Related Systems

摘要本研究主要研究具有一系列低维M- o -M' （M = Re或Mo， M' =晚期过渡金属）和M- o -M键合网络的新型还原氧化铼和氧化钼/有机杂化物的合成、结构表征和物理性质。合成的努力将推进水热技术的使用，以产生具有电子性质和/或金属-金属键的新型还原杂化物，这些杂化物也可以动态耦合到选择性小分子插层和氧化还原活性。杂化固体将代表一种新型的多功能电子材料，也将有助于更深入地了解还原铼酸盐和钼酸盐中导致磁电和超导特性的电子-电子相互作用。由此产生的在灵活的框架内控制或调整分子/原子水平上的电子-电子相互作用的能力，对于直接实现许多新的电子设备应用具有巨大的潜力。教育部分涉及到K-8，本科和研究生水平的大量不同的学生，并将提供许多宝贵的固态化学经验（例如新的课堂演示和研究文章讨论）。该项目还将为研究生提供先进研究技术方面的宝贵专业培训，包括固态合成、表征和物理性质测量。目前设想了许多未来的固态电子设备，但这取决于对固体中电子之间相互作用的更好理解，以及如何以新的多功能格式利用它们。例如，为了学习如何利用电子的自旋方向来加速逻辑运算或增加数据存储容量，或者为了无电阻电流的流动，新的研究是必要的。研究计划围绕着这些总体目标，并以各种灵活的固态结构为目标，基于有机物质与铼和钼氧化物的协同结合，这些结构具有以前从未用于探测电子特性的先进功能和灵活性。此外，多功能氧化物/有机固体将代表在分子/原子水平上获得电子特性控制的新的重要途径，并有望在未来的电子设备中应用。研究生将在先进的研究技术方面获得宝贵的专业培训，包括固态合成、表征和物理性质测量。该项目还包括在课堂上安装前沿研究实例和演示，以帮助增加对固态化学研究对社会的重要贡献的理解和认识。

Technical AbstractThis research project focuses on the syntheses, structural characterization, and physical properties of new reduced rhenium and molybdenum oxide/organic hybrids that possess a range of low dimensional M-O-M' (M = Re or Mo, M' = late transition metal) and M-O-M bonded networks. The synthetic efforts will advance the use of hydrothermal techniques to yield the new reduced hybrids with electronic properties, and/or metal-metal bonding, that can also be dynamically coupled to selective small-molecule intercalation and redox activity. The hybrid solids will represent a new type of multifunctional electronic material, and as well, will help lead to a deeper understanding of the electron-electron interactions that are responsible for magnetoelectric and superconducting properties in reduced rhenates and molybdates. Resultant abilities to control or tune the electron-electron interactions at the molecular/atomic level within a flexible framework hold great potential for directly enabling many new electronic device applications. The educational component reaches out to a large and diverse base of students at the K-8, undergraduate and graduate levels, and will provide for many valuable experiences (e.g. new classroom demonstrations and research article discussions) in solid-state chemistry. The project will also provide research students with valuable professional training in advanced research techniques, including in solid-state syntheses, characterization, and physical property measurements.Non-Technical AbstractMany future solid-state electronic devices are currently envisioned but that depend on a better understanding of the interactions between electrons within solids as well as how to utilize them in new multifunctional formats. For example, new research is necessary in order to learn how to employ the spin orientation of an electron to speed logic operations or to increase data storage capacities, or alternatively, for the resistance-free flow of electrical current. The research plans are centered around these overarching objectives, and aim toward a diverse range of flexible solid-state structures, based on the synergistic incorporation of organics into rhenium and molybdenum oxides, that possess an advanced functionality and flexibility that has never previously been utilized to probe electronic properties. Further, the multifunctional oxide/organic solids will represent a new and significant gateway for gaining control over the electronic properties at the molecular/atomic level, and that hold promise for enabling their application in future electronic devices. Research students will gain valuable professional training in advanced research techniques, involving solid-state syntheses, characterization, and physical property measurements. The project also includes the installment of cutting-edge research examples and demonstrations into the classroom, to help increase the understanding and awareness of the important contributions of solid-state chemistry research to society.
