Research Interests

Organic, Materials, Organometallic, and Optical Science. Our research program focuses on understanding how the chemical structures of molecules and materials relate to their electronic and optical properties. We employ a molecular approach in which fundamental structure-property relations are defined through a coordinated synthesis, theory and characterization program. In particular, we seek to develop a fundamental understanding of how to control the interactions of light and matter, and use this understanding to design and synthesize molecules and material for applications in photonics, materials processing, biology, and medicine. We collaborate with theoretical, physical, and analytical chemists, optical scientists, and biologists providing researchers a multidisciplinary training.

Two Photon Chemistry. We are interested in dyes that simultaneously absorb two photons to create excited states that lie at the energy sum of the two absorbed photons above the ground state. Such dyes allow one to excite molecules with very high spatial selectivity only at the focus of a laser beam. Recently, in collaboration with Professor Perry, we have found that molecules with donor-acceptor-donor (D-A-D) (below left), and acceptor-donor-acceptor (A-D-A) (below right) structural motifs exhibit exceptionally large two-photon absorptivities. We are now designing and synthesizing two-photon absorbing molecules and materials with additional chemical and optical activity. For example, newly developed two photon dyes can initiate polymerization of several monomers, for "writing" complex three-dimensional polymer structures. We are developing material systems for 3-D optical storage such that a terabit of information can be stored in the volume of a sugar cube. In collaboration with biologists we are synthesizing dyes (below left) to image biological structure and function with three-dimensional resolution optically; for example, using dyes that can be conjugated with antibodies through biotin-strepavidin interactions.

Materials for Photonics and Displays. We are developing organic and organometallic material systems (see below) that in response to optical, and/or electrical signals change their refractive indices. This allows the material to switch or modulate a light beam or record holographic images in real time. We are also interested in developing molecules and polymers for both liquid crystal displays and organic LEDs.
