We are interested in the design and synthesis of all kind of functional p-conjugated materials with unique electronic/optical properties. Mainly, such materials will be applied for optoelectronic devices such as organic light emitting diode (OLEDs), organic solar cells, and organic field effect transistors (OFETs). Our research is focused on molecular engineering to improve device performance. 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.
- Carbonaceous solids, including fullerene, carbon nanotube, and graphene, have attracted extensive attention from the physics, chemistry, and materials science communities because of their unique electronic and mechanical properties. Therefore, we are focusing on developing various chemical modification of the carbonaceous solids for electronic applications. Besides, we are currently studying supramolecular chemistry.
- Thereby, the mission of our group is to advance the science and engineering of organic and hybrid nanostructured materials and enable technological innovations for applications in communications, sensing, displays, energy efficient solid-state lighting, and power generation. New products based on organic semiconductors will save energy, reduce costs, be lightweight and flexible, increase national security, and enhance the quality of the environment.
- The undergraduate, graduate students, postdoctorals, and research scientists working in our group are exposed to a multidisciplinary and diverse environment that is a blend of optics, physics, chemistry, materials science, and electrical engineering.
