  1. 4-acetylpyridine acetone 4-dimethylaminopyridine DMF Novel Open Frameworks of Metals, Metal Complexes, or Metal Clusters Interconnected with Multifunctional LinkersSlavi C. Sevov, University of Notre Dame, DMR 0600320 Our research focuses on synthesis and characterization of novel inclusion compounds where the host framework is made of a cationic metal complex and an anionic organic disulfonate held together by multiple charge-assisted hydrogen bonds. Such hosts can be used for capturing and encapsulating various organic molecules from different environments. We have synthesized a series of such frameworks made of [Co(NH3)6]3+ or [Co(en)2(ox)]+ and 4,4'-biphenyldisulfonate. Their structures are of the pillared-layer type (below) where the guest organic molecules occupy the galleries between the pillars. The host structures adjust in order to accommodate the steric, electronic, and hydrogen-bonding needs of the guest molecules. Shown below are examples of four different host frameworks with guests of acetone, 4-acetylpyridine, DMF, and 4-dimethylaminopyridine. All these host-guest frameworks are analogs to the well-studied guanidinium sulfonate networks and mimic their flexibility and overall durability.

  2. Novel Open Frameworks of Metals, Metal Complexes, or Metal Clusters Interconnected with Multifunctional LinkersSlavi C. Sevov, University of Notre Dame, DMR 0600320 • Broader Impact • Education and Mentoring • Graduate Students: Two graduate students, Michael Scancella and Rachelle Justice, obtained M.S. degrees in the Summer of 2006: • Postdoctoral Fellows: Two postdoctoral fellows, Xin-Yi Wang and Tori Forbes, are involved with the project. • Undergraduate Students: Two undergraduate students sponsored by the NSF summer program in Solid-State Chemistry (DMR-0303450), David Boyce and Justin Martinchek, were also involved in the project. • Teaching • A new graduate/undergraduate course was developed in connection with this grant. The course titled "Structural chemistry as a bridge between geological solids and man-made materials" was offered for the first time in the Spring of 2007. It was designed and taught together with Peter Burns from the Department of Geological Sciences and Lynda Soderholm from the Argonne National Laboratory. International Activities • I was invited to serve on the International Advisory Board for the Scientific Partner Group between the Max-Planck Institute (Dresden) and the Shanghai Institute of Ceramics (Chinese Academy of Sciences). • I was invited to participate in an IUPAC committee charged with developing nomenclature for the borophosphate compounds.
