This goal of this project is to synthesize and characterization the structure and properties of novel f-metal containing organic/inorganic hybrid materials. These compounds, in particular the metal-organic framework materials (MOFs), have importance and potential applications to areas such as spent nuclear fuel storage, magnetic and optical materials, sensing, catalysis, and separations. Novel approaches to the generation of these materials are presented and include the use of heterofunctional ligands to promote heteronuclear compounds, organic template 'aging' to control the oxidation states of the metals and examination of formation pathways using time-resolved in situ x-ray diffraction at synchrotron facilities. By design, this research program contains a particular commitment to the education and training of students at both the graduate and undergraduate levels. Various degrees of participation incorporated into this research project include fundamental and/or exploratory syntheses and characterization efforts designed for undergraduates, as well as longer term projects for graduate students that include establishing crystal chemical systematics and structure-property relationships.%%%This research project aims to synthesize and characterize novel organic/inorganic hybrid materials for potential applications areas such as catalysis, molecular recognition and separation, sensing, electronic materials and environmental stewardship and remediation. The research project is designed specifically for the involvement of undergraduate and graduate students and maintains a particular commitment to educating and training the next generation of scientists and critical thinkers. Students will be exposed to cutting-edge research techniques such as novel synthesis routes and 'big science' facilities found at National Laboratories. Public support of this effort is justified considering the tangible scientific output, as well as the longer-term investment in the education of its participants.***

本计画的目标是合成含氟金属的有机/无机杂化材料，并对其结构与性质进行表征。 这些化合物，特别是金属有机骨架材料（MOFs），在乏核燃料贮存、磁性和光学材料、传感、催化和分离等领域具有重要的应用前景。提出了产生这些材料的新方法，包括使用杂官能配体来促进杂原子化合物，有机模板“老化”来控制金属的氧化态，并使用时间分辨原位X射线衍射在同步加速器设施检查形成途径。 通过设计，这项研究计划包含了一个特别的承诺，在研究生和本科生水平的学生的教育和培训。 本研究项目的参与程度不同，包括为本科生设计的基础和/或探索性合成和表征工作，以及为研究生设计的长期项目，包括建立晶体化学系统学和结构-性质关系。该研究项目旨在合成和表征新型有机/无机杂化材料，用于催化，分子识别和分离，传感，电子材料和环境管理和修复等潜在应用领域。该研究项目是专门为本科生和研究生的参与而设计的，并保持对教育和培训下一代科学家和批判性思想家的特别承诺。 学生将接触到尖端的研究技术，如新的合成路线和“大科学”在国家实验室发现的设施。 考虑到有形的科学产出以及对参与者教育的长期投资，公众对这一努力的支持是合理的。
