Our research group is broadly interested in tailoring the molecular structure of conjugated organic polymers in order to control the fundamental properties of the bulk materials. Our polymers are designed, synthesized and tested for use in applications ranging from biomaterials to organic electronics. Conjugated polymers are of great interest as they are able to conduct electricity through their extended pi-system but are softer and more flexible than metals or other inorganic semiconductors such as silicon. Therefore, conducting polymers can offer distinct advantages when used in biological stimulation applications, as their mechanical properties can be tuned to match that of biological tissues leading to better integration and lower levels of tissue trauma. Likewise, replacing traditional materials with conducting polymers has led to the development of flexible and lightweight electronic displays and photovoltaic devices that would have otherwise been impossible to create.
