Chem Image Organic polymers can be made with a broad range of useful electrical and optical properties. In our research we investigate how the molecular and supramolecular structure affects these properties and use that knowledge to design and synthesize polymers. We seek polymers with high electronic and ionic conductivities, along with redox active electrochromism and biomolecule release. We also study transition metal complex-containing polymers that act as infrared radiation filters and sensors, along with conjugated polymers that are water soluble and can be utilized in a number of electronic and optical devices.

Chem Image Various transition metal mediated coupling polymerization methodologies are used to prepare p-phenylene and heterocycle-containing conjugated polymers. Recently, we have succeeded in preparing electroluminescent polymers that can be processed from environmentally useful aqueous solutions. By directly appending this bis-salicylidene metal complexes to the backbones of polythiophenes, electroactive polymers with redox chemistry sensitive to electron-donating species in solution have been prepared and can be considered as new sensor materials.

Electrochromic polymers, which can be either anodically or cathodically coloring, and exhibit colors over the entire visible spectrum are under study. Utilizing oxidatively polymerizable 3,4-alkylenedioxythiophene based monomers (our XDOT monomers) we are able to tailor both optical and electrochemical properties. These polymers exhibit extremely rapid switching rates and electrochromic contrasts necessary for switchable window and display applications.
