Tris(hydroxypropyl)phosphine Oxide: A Chiral 3D Material with Non-linear Optical Properties

Alec C. Durrell, Harry B. Gray, Nilay Hazari,* Christopher D. Incarvito, Jian Liu and Elsa C. Y. Yan

The achiral C3v organic phosphine, tris(hydroxypropyl)phosphine oxide, crystallizes in the unusual chiral hexagonal space group P63. The structure is highly ordered because each phosphine oxide moiety forms three hydrogen bonds with adjacent hydroxy groups from three different molecules. The properties of the crystals and the presence of hydrogen bonding interactions were investigated using single crystal Raman spectroscopy. The crystals show non-linear optical properties and are capable of efficient second harmonic generation.

Reshaping the Synthesis of Porous Crystals for  Molecular Storage and Separations

Adam Matzger University of Michigan

Adsorbents play a critical role in a variety of industrial, laboratory and consumer applications. Materials such as silica gel, zeolites, and activated carbon have been investigated for centuries and represent the most commonly used adsorbents. In the last decade new structurally defined high surface area materials based on coordination chemistry have emerged. These inorganic-organic hybrid materials are promising to redefine the types of processes and applications that can be enabled by adsorption. Synthetic challenges, structural characterization, and novel approaches relating to microporous coordination polymers (MCPs) will be discussed. Recent progress with coordination copolymerization and reduced symmetry linkers will be presented in the context of ultrahigh surface area materials. Application of MCPs for storage of gases will be emphasized followed by novel applications in liquid phase separation.
