Research Overview
Following traditional chemical engineering programs in the early 1980's through the early 1990's, organic optoelectronic materials have constituted the core of our research thereafter encompassing molecular design, computational chemistry, materials synthesis and processing, and optoelectronic device applications. In particular, we have developed liquid crystals, including monodisperse 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) cholesteric glassy liquid crystals as circular polarizers for a novel night-vision technology; (2) mesomorphic ceramic films for polarization control of powerful lasers; (3) geometric surfactancy as a new concept beyond traditional amphiphilicity; and (4) sustainable synthesis and processing of advanced optical materials.
