Conjugated Polymers for Electrochromic, Light Emitting, and Photovoltaic Devices

Our group has a coordinated synthesis, properties control, and device platform effort directed to developing variable band gap pi conjugated polymers which may find utility in a variety of optoelectronic devices. Using electron rich and electron rich heterocycles polymerized via various transition metal mediated coupling and electrochemical methods, polymers are designed with controlled HOMO and LUMO energy levels and electronic band gaps. This provides electronic absorption and emission properties controllable from the UV, through the visible, the near-infrared and even longer wavelengths. We seek to optimize the properties of polymers as they may be applied to color changing electrochromics, visible and near-infrared light emission, and flexible organic polymer based solar cells.
