Design Strategies for Lamellar Materials, or "What I've
Engineered for You Lately". Alicia M. Beatty, Dept. of Chemistry and
Biochemistry, University of Notre Dame, Notre Dame, IN 46556
One of the challenges in the supramolecular assembly of solid
materials is to find reliable building materials – molecules or ions that
will interact in a predictable, consistent manner. In this case, we have
assembled lamellar materials from 3,5 pyrazole dicarboxylic acid
(H2PzA) by linking parallel sheets of the HPzA monoanion via
hydrogen bonds. This lamellar assembly can accommodate substituents and/or
guest species of a variety of shapes and sizes (and with a potential for a
variety of weak interactions, e.g. pi-pi, Cl-Cl) between the layers.
Can we translate the design principles of an organic lamellar
construction to an inorganic/organic hybrid material? If so, we will be able to
design and synthesize lamellar inorganic/organic hybrid materials with removable
guests and/or labile ligands for catalysis.
