I am an inorganic chemist. Inorganic chemistry is the study of compounds based on elements other than carbon. Strange as it may seem, many inorganic compounds (including virtually all of the ones we study) have carbon-based groups in them. The distinction between inorganic and organic compounds is sometimes a matter of taste, but if there's at least one metal atom in a compound, it's inorganic to me. Inorganic compounds are found in the earth (minerals, metal ores, metals, clays), in the water (dissolved salts) and air around us, in living things (salts, metal-containing proteins, such as hemoglobin, bone), and in countless consumer products (metals, semiconductors, concrete, glass). My specific research interests are in the fields of inorganic polymers, organometallics, and X-ray crystallography.

RESEARCH INTERESTS

Inorganic Polymers. We are interested in producing new inorganic polymers which have metal atoms within the backbone of the polymer chain. Depending on their chemical construction, these polymeric networks may be chain-like (one dimensional), sheet-like (two dimensional), or fully networked (three dimensional). Metal-organic networks have potential applications as luminescent materials for displays and sensors, as porous materials for separations work, and as catalysts for use in organic reactions. 

X-ray Crystallography. The repeating pattern of atoms that exists in a crystalline substance contains a wealth of information. Crystals are composed of nanometer-scale repeat units, called unit cells. When a tiny crystal is bathed in an X-ray beam, the X-rays diffract off of the layers of atoms present in the crystal. The pattern of diffracted X-ray spots can be reconstructed to yield a map of the positions of atoms in the unit cell. The pictures at the top of this page are "photos" of molecules solved by X-ray crystallography in our laboratory.

X-RAY CRYSTALLOGRAPHY CENTER

Our group is active in solving X-ray crystallographic structures for chemists at other primarily undergraduate Colleges and Universities. If you would like to know more about this program please the X-ray Crystallography Center web site .

RESEARCH GROUP

I typically work with 4 to 7 research students at a time. Many of these students spend at least one summer in my laboratory.

 

My summer 2008 research group: Me, Mandy Ley ('09), James Jones ('10).
