Research Overview

Following traditional chemical engineering programs in the early 1980s through the early 1990s, organic optoelectronic materials have constituted the core of our research since the mid-1990s encompassing molecular design, computational chemistry, materials synthesis and processing, and optoelectronic device applications.  In particular, we have developed liquid crystals, including monodisperse p-conjugated systems, capable of preserving molecular order in glassy state with elevated transition temperatures 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) Sustainable synthesis and processing of advanced optical materials; and (4) Robust optical and photonic devices comprising glassy liquid crystals on photoalignment layers for high peak-power laser applications.
