Research Interests


We are interested in design, synthesis and characterization of organic optoelectronic materials. In comparison with their inorganic counterparts, organic optoelectronic materials are much more processing friendly and offer lower cost and structural versatility. Our research interests in this area are:


Polymeric photovoltaic materials for solar cells

We are seeking for polymeric photovoltaic materials with high solar-electric energy conversion efficiencies as the renewable, environmental-friendly solution to our ever-increasing energy needs.

In order to achieve energy-conversion efficiency high enough to compete with inorganic photovoltaic materials, we design and synthesize macromolecules that possess

1. High photon collection efficiency;
2. High charge generation efficiency;
3. High charge-transport and collection efficiency.

Rationally designed polymer materials with precisely engineered molecular and supramolecular structures will lead to the optimized photovoltaic properties. For example, we arrange charge transport materials in well-controlled nano-scaled structures for high charge-transport and collection efficiencies.


Charge-Transport Liquid Crystals (CTLC)

CTLCs have important applications in organic devices such as field effect transistors, light emitting diodes and photovoltaic cells. With combined molecular order and mobility, CTLCs can offer high charge carrier mobilities as well as flexibility and self-healing ability.

We are interested in CTLCs with stable liquid crystalline phases over a wide temperature range including room temperature. We apply structural modification to optimize the electronic/transport properties of CTLCs for holes and electrons, respectively. The hierachical structure-property relationship of CTLCs are investigated and utilized to guide the design of CTLCs with improved properties.

Conducting Polymers
  1. Synthesis and characterization of highly conjugated, high refractive index polymers for photonic applications
  2. Synthesis and characterization of low-band gap conducting polymers that are solution processible, transparent and intrinsically conducting

Polymer Alignment Materials for Liquid Crystals

Polymer alignment materials that provide strong anchoring effect to liquid crystal molecules for fast-response liquid crystal displays.
