Research in our laboratories often combines synthetic and
physical inorganic chemistry with polymer science through
problems that appeal simultaneously to both disciplines.
Chemistry for "Light Work": Advanced optical information technologies provide incentive for
us to develop new chemistry to control or respond to light, and new integrated optics (IO)
spectroscopy to probe fundamental thin film and interfacial chemical and physical events.
Many polymer and inorganic materials can be processed into active or passive integrated
optical circuits that guide light. Linear and nonlinear laser spectroscopy in these circuits
allows us to gather information about photon-matter interactions crucial to our
understanding of thin films, interfaces, and of materials for photon-based technologies.
Subjects studied are self organization, interfacial chemistry, photochemistry,
photoalignment, chiroptical media, fractals, mesoscopic systems, monolayers, wetting,
adsorption and molecular frictional forces. Students model and construct optical devices,
converting them into minute "optical chemical benches" for spectroscopy. There is strong
emphasis on the chemistry of nanolithography, photorefractive and holographic materials,
molecular auto-assembly, mesoscopic systems, and sol-gel glasses. Materials chemistry
applications focus on waveguide lasers, optical amplifiers, sensors and photonic integrated
circuits. Associative logic and bio-optical devices from molecular chemistry are long term
research objectives.
Condensed Matter from Free Atoms and Molecular Fragments: This component of our
research explores the synthetic utility of atoms or energetic molecular inorganic fragments
produced by electron beam or thermal vaporization. Polymerization, catalysis, nanophase
composite, magnetic, semiconductor and ceramic materials synthesis, metastable solid
synthesis and small molecule chemical bond activation are themes of this research. These
studies are often supported by rare gas solid cryogenic matrix isolation spectroscopy of
incipient atom-molecule reactions. Vibrational, electronic, synchrotron radiation scattering,
nonlinear optical, photoelectron and paramagnetic resonance spectroscopy are assisted by
high level, spin density electronic structure calculations. Further information can be found
in the Inorganic Division brochure.
