Frameworks of Transition Metals and Multifunctional Linkers

将合成基于各种多官能连接剂的具有开放骨架结构和改进性能的新型无机/有机杂化材料。对过渡金属-多官能团连接体体系的重视将导致具有新结构和新性质的新型开放骨架化合物的产生。例如，硼磷酸基团，一种具有硼酸盐和磷酸盐官能团的多官能“连接体”，是一种新的物质，其在某些化合物中的作用类似于铝磷酸盐，但在其他化合物中带来独特的结构特征。该项目的设想是通过使用与已知开放框架化合物的类比来进一步利用这种能力，其中将系统地研究各种模板，过渡金属和合成条件。待研究的其他多官能连接剂包括二膦酸酯、羧基膦酸酯和膦酸化α-氨基酸，以向过渡金属中心提供各种配位模式以及向固体提供不同的官能度。参与该项目的学生将获得结构表征，性能测量和新合成技术方面的宝贵技能。他们在尖端研究方法的培训是强调。%无机/有机杂化材料在分子分离和传感、离子交换、石油化工催化和化学品生产中具有巨大的应用潜力。后者的技术影响将是改进化学加工，从而提高能源使用效率。该计划的教育方面旨在教授本科生和研究生，不仅在特定的实验室技术，而且在一般的理解和欣赏固态化学。这些领域的培训将使这些化学家在大学和化学工业中具有很强的竞争力。

New hybrid inorganic/organic materials with open-framework structures and improved properties based on various multifunctional linkers will be synthesized. The emphasis on transition-metal - multifunctional linker systems will lead to new open-framework compounds with new structures and novel properties. For example, the borophosphate group, a multifunctional "linker" with borate and phosphate functionalities, is a novel species that acts similarly to the aluminophosphates in some compounds, but brings unique structural features in others. Envisioned for this project is further utilization of such capabilities by using analogies with known open-framework compounds where various templates, transition metals, and synthetic conditions will be systematically studied. Other multifunctional linkers to be investigated include di-phosphonates, carboxy-phosphonates, and phosphonated a-aminoacids to provide various coordination modes to the transition metal centers as well as different functionalities to the solid. Students involved with this project will acquire valuable skills in structure characterization, property measurements and novel synthetic techniques. Their training in cutting-edge research methodology is emphasized.%%%Inorganic/organic hybrid materials have significant potential for applications in molecular separation and sensing, ion exchange, and catalysis in the petrochemical industry and for chemicals production. The technological impact of the latter will be in improvements in chemical processing and, subsequently, an increase in energy-use efficiency. The educational aspect of the program is aimed at teaching undergraduate and graduate students not only in particular lab techniques but also in general understanding and appreciation of solid state chemistry. Training in these areas will make these chemists highly competitive for employment in universities and in chemical industry.
