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：将合成并表征由过渡金属或过渡金属配合物制成的具有中性开放框架结构的新型材料，这些材料通过多功能有机连接剂互连。连接体主要是磺酸盐或二磺酸盐，通常与羧基和氨基结合，并且还将使用膦酸盐和羧酸盐。许多系统将涉及阳离子过渡金属络合物和阴离子磺酸盐之间的多重电荷辅助氢键；其他活动还将涉及与过渡金属中心的直接协调。 这项研究得到了材料研究部固态与材料化学项目的支持，旨在发现具有新型无机-有机框架结构的多种材料，这些材料根据其无机（磁性、光学、机械和热稳定性等）和有机（多样性、结构灵活性等）部分表现出不同的性能。这种潜在的特性整合使得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、结构表征和性能测量将为研究生和本科生提供尖端工具和方法的培训机会，以进行固态化学和溶液化学研究。该项目与圣母大学现有的基础设施和招收弱势群体学生的计划相结合，将用于吸引少数族裔和女性同事。非技术摘要所提出的具有开放框架结构的新型材料将影响经济的各个重要领域，例如新型催化剂、用于分离和离子交换的新型膜材料、石油裂化、纳米技术以及光学和传感器材料的开发。 其中许多应用反过来将带来更好的化学加工和更高的能源利用效率。一个例子是这些材料可能用作气体储存和运输的安全且环保的容器。该项目还将提供受过高等教育且经过实践培训的博士学位。学生和博士后研究员推动科学和工程前沿的高质量研究。
