Our Research



   Our research is focused on the synthesis of pi-conjugated organic materials for organic electronic applications. These materials are often composed of organic dyes, leading to highly coloured products with strong absorption properties ideal for light harvesting applications. The synthetic protocols of our research group are centered around developing more sustainable synthetic measures and incorporating low-cost materials. To this effect, the use of heterogeneous catalysts and direct heteroarylation have become common practice for assembling the majority of our pi-conjugated materials.



  The solution processability of organic pi-conjugated materials allows for the formation of semiconducting thin films enabling low-cost electronic devices. Critical to achieving high performance devices is the proper organization of such active organic materials in the solid state. An active area of research in our group is the understanding of materials self-assembly and the use of chemical modification to control this self-assembly to realize highly ordered nanostructures. 



  The pi-conjugated materials designed and synthesized in our research group are used as active materials in organic electronic devices. The lab is interested in solar cells, light emitting diodes, transistors, electrochromics, biosensors, chemical sensors, and CO2 conversion devices. The overall theme is printed electronics for energy, health, and the enviroment.
