Functional organic materials have attracted significant attention over the last two decades as electro-active materials for the development of printable and flexible electronic devices such as organic thin-film transistors (OTFTs), light-emitting diodes (OLEDs), light-emitting transistors (OLETs), and photovoltaic cells (OPVs). Owing to their unique features over traditional inorganic materials, they are envisioned as essential components for several next-generation optoelectronic applications including low-power flexible displays/electronic papers, wearable electronics, printable RFID tags/sensors, and flexible solar panels.

20th century has been the era of mastering chemistry to realize modern functional materials. Based on our group's academic and industrial research expertise in organic optoelectronics, now we’re using chemistry, materials science and nanotechnology to build state-of-the-art, high-performance organic optoelectronic materials of the 21st century.

Our research is focused on the theoretical design and synthetic development of new organic molecular and polymeric π-conjugated materials for next-generation optoelectronic devices. In particular, we are interested in molecular/polymeric semiconductors, photocurable dielectrics, surface modifiers, donor/acceptor polymers and emissive host/guest systems.
