TECHNICAL SUMMARY:Novel materials with neutral open-framework structures made of transition metals or transition-metal complexes that are interconnected with multifunctional organic linkers will be synthesized and characterized. The linkers will be mainly sulfonates or disulfonates, often combined with carboxy- and amino-groups, and phosphonates and carboxylates will be used as well. Many of the systems will involve multiple charge-assisted hydrogen bonding between cationic transition-metal complexes and the anionic sulfonates; others will also involve direct coordination to the transition-metal centers. This research, supported by the Solid State and Materials Chemistry program of the Division of Materials Research, aims at discovering diverse materials with new inorganic-organic framework structures that exhibit diverse properties based on their inorganic (magnetic, optical, mechanical and thermal stability, etc.) and organic (diversity, structural flexibility, etc.) parts. This potential integration of the properties makes these compounds of great interest for a wide range of potential applications. The synthetic techniques, structure characterization, and properties measurements will provide opportunities for training graduate and undergraduate students in cutting-edge tools and methodologies for doing research in both solid-state chemistry and solution chemistry. The project, in combination with the existing University of Notre Dame infrastructure and programs for recruiting students from underrepresented groups, will be used to attract minority and female coworkers. NON-TECHNICAL SUMMARY The proposed novel materials with open-framework structures will impact various important areas of the economy such as the development of new catalysts, new membrane materials for separation and ion exchange, petroleum cracking, nanotechnology, and optical and sensor materials. Many of these applications will, in turn, lead to better chemical processing and to higher energy-use efficiencies. An example is the potential use of these materials as safe and environmentally benign containers for gas storage and transportation. The project will also provide highly educated and practically trained Ph.D. students and postdoctoral fellows to advance high quality research at the forefront of science and engineering.

技术摘要：将合成和表征与多功能有机接头互连的过渡金属或过渡金属配合物制成的中性开放式框架结构的新型材料。接头将主要是磺酸盐或二硫酸盐，通常与羧基和氨基群结合，并且也将使用磷酸盐和羧酸盐。许多系统将涉及阳离子过渡金属复合物和阴离子磺酸盐之间的多个电荷辅助氢键。其他人还将涉及到过渡金属中心的直接协调。 这项研究得到了材料研究划分的固态和材料化学计划的支持，旨在发现具有新的无机有机框架结构的多种材料，这些结构基于其无机（磁性，光学，机械和热稳定性等）表现出多种特性，并具有多样性（多样性，结构性灵活性等）部分。这些属性的潜在整合使这些化合物在广泛的潜在应用中引起了极大的兴趣。合成技术，结构表征和性质测量结果将为培训研究生和本科生提供尖端工具和方法的机会，以从事固态化学和溶液化学研究。该项目与现有的圣母大学基础设施和计划招募来自代表性不足的团体的学生的计划将用于吸引少数民族和女性同事。非技术总结使用开放式结构的拟议新材料会影响经济的各个重要领域，例如开发新的催化剂，新的分离和离子交换膜材料，石油裂纹，纳米技术以及光学和传感器材料。 这些应用中的许多应用将导致更好的化学加工和提高能源效率。一个例子是将这些材料作为安全且环境良性的容器用于气体存储和运输。该项目还将提供受过良好教育且实际培训的博士学位。学生和博士后研究员在科学与工程的最前沿提高了高质量的研究。
