技术摘要本研究项目致力于具有一系列低维M-O-M‘(M=Re或Mo，M’=后过渡金属)和M-O-M键网络的新型还原Re和MoO2/有机杂化化合物的合成、结构表征和物理性质。这些合成工作将推进水热技术的使用，以产生具有电子性能和/或金属-金属键的新的还原杂化化合物，这些杂化化合物还可以动态耦合到选择性的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，也将有助于加深对电子-电子相互作用的理解，这些相互作用是还原Rh酸盐和钼酸盐中产生磁电和超导性质的原因。因此，在灵活的框架内在分子/原子水平上控制或调节电子-电子相互作用的能力，为直接实现许多新的电子设备应用提供了巨大的潜力。教育部分涉及到大量不同的K-8级、本科生和研究生，并将提供固态化学方面的许多宝贵经验(例如，新的课堂演示和研究文章讨论)。该项目还将为研究型学生提供有价值的高级研究技术方面的专业培训，包括固态合成、表征和物理性质测量。非技术摘要目前正在设想许多未来的固态电子设备，但这取决于对固体中电子之间的相互作用以及如何以新的多功能形式利用它们的更好理解。例如，有必要进行新的研究，以了解如何利用电子的自旋取向来加速逻辑运算或增加数据存储容量，或者替代地，用于电流的无电阻流动。研究计划围绕这些总体目标，旨在开发一系列灵活的固态结构，基于将有机物协同结合到Re和Mo氧化物中，这些结构具有以前从未用于探测电子性质的高级功能和灵活性。此外，多功能氧化物/有机固体将成为在分子/原子水平上控制电子性质的新的重要途径，并有望使其在未来的电子器件中得到应用。研究型学生将获得有价值的高级研究技术方面的专业培训，包括固态合成、表征和物理性能测量。该项目还包括将尖端研究范例和演示带入课堂，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.
