Achievement

IGERT Fellow, John Cowart, collaborated with IGERT researcher Craig Hawker and the McCulloch and Heeney groups of Imperial College, London. The motivation for this work was the development of organic semiconducting active layers that combined the advantages of bi-layer and bulk heterojunctions. Several low bandgap conducting polymers were fashioned with crosslinkable oxetane pendant groups. These polymers were based on cyclopentadithiophene benzothidiazole backbones and were designed to be solution processed, stamp imprinted, and crosslinked to yield donor layers with high surface area. Organic electronic devices are currently being made with these materials and more detailed results of their device performance are forthcoming.
