Research Summary

Our research features molecular design, computational chemistry, material synthesis and processing, and optoelectronic device science. In particular, we have developed liquid crystals, including conjugated systems, capable of preserving molecular order in the solid state through vitrification while ensuring long-term stability against crystallization. Various device concepts have been demonstrated using selected materials, such as nonabsorbing polarizers, notch filters and reflectors, polarized fluorescence and electroluminescence, field-effect transistors, solid-state lasers, and photoalignment of conjugated oligomers. Current activities include: (i) bipolar hybrid hosts for phosphorescent organic light-emitting diodes, (ii) a new concept of surfactancy based on geometric disparity within molecules, (iii) pixelated liquid crystal devices for shaping laser beams, and (iv) high throughput, precise production of double and triple microemulsions using microfluidic T-junctions.
