Welcome!

Our research is in the area of materials chemistry and physics of complex, soft materials. Specifically, we are interested in electrically-active polymeric and molecular materials.  We hope to elucidate the fundamental processing-structure-property relationships that govern these materials to generate design rules and guidelines for the rational synthesis of materials with tailored properties and the development of innovative processing and patterning technologies for the realization of low-cost, light weight, mechanically flexible thin-film devices, such as organic transistors and solar cells.

Currently, we are examining how specific processing conditions affect the structure evolution of organic and polymer materials, and how structural development can in turn impact applications-relevant macroscopic electrical and physical properties. Work is being carried out on molecular and polymeric semiconductors, conducting polymers, solution-synthesized and structurally precise graphene nano ribbons, as well as organic-inorganic hybrid perovskites.

High Performance OTFTs Fabricated Using a Calamitic Liquid Crystalline Material of 2-(4-Dodecyl phenyl)[1]benzothieno[3,2-b][1]benzothiophene

In collaboration with researchers at Peking University at Shenzhen, we recently demonstrated high performance organic thin-film transistors with high thermal stability that incorporate an air-stable calamitic liquid crystalline molecular semiconductor.
