Research Overview

  

Organic materials constitute the core of our research encompassing molecular design, computational chemistry, materials synthesis and processing, and optoelectronic device applications.  In particular, we have developed liquid crystals, including conjugated systems, capable of preserving molecular order in glassy state while ensuring long-term stability against crystallization.  Various device concepts have been demonstrated using selected materials, e.g. nonabsorbing polarizers, notch filters and reflectors, polarized electroluminescence, field-effect transistors, solid-state lasers, and robust photoalignment films for orienting both fluid and glassy liquid crystals.  Current activities include: (1) Geometric surfactancy as a new concept beyond traditional amphiphilicity; (2) Thermodynamic and kinetic analysis of particle ordering to enable effective nanomaterials processing; (3) Transition temperatures of glassy liquid crystals through computation; and (4) Laser-damage-resistant distributed polarization rotators comprising glassy liquid crystals on photolignment layers.
