Research Interests
We are interested in the design and synthesis of all kind of functional pi-conjugated materials with unique electronic/optical properties. Mainly, such materials will be applied for optoelectronic devices such as organic light emitting diode (OLEDs), organic photovoltaics (OPVs) and organic field effect transistors (OFETs). Our research is focused on molecular engineering to improve device performances. We have close collaboration with strong device engineering and device architecture groups. Currently, we are not only interested in a kind of nano-sized molecules and related structures, their synthesis, self-assembly and processing/device fabrication.
