1. High charge carrier mobility, low bandgap Donor-Acceptor benzothiadiazole-oligothiophene based polymeric semiconductorsElsa Reichmanis, Georgia Tech Research Corporation, DMR 1207284 A series of polymeric semiconductors having a low bandgap were designed and synthesized. The resulting materials were thermally stable up to ca. 400 °C and optical characterization suggests that the polymers may effectively absorb photons in the entire range of the visible spectrum (400 - 800 nm). The semiconducting materials were incorporated into field-effect transistor devices to evaluate their macro-scale electronic properties. One particular polymer identified as “PBT6” exhibits high charge carrier transport properties comparable to amorphous silicon. Studies revealed a correlation between the transport properties of the materials prepared in this investigation with their crystallinity.

2. High charge carrier mobility, low bandgap Donor-Acceptor benzothiadiazole-oligothiophene based polymeric semiconductorsElsa Reichmanis, Georgia Tech Research Corporation, DMR 1207284 This grant supports the efforts of one graduate and one undergraduate student working on the highlighted project. Further, collaborations with the Henderson and Collard groups at Georgia Tech have been established and the research utilized the X-ray Scattering Facility at the University of Minnesota, which receives partial support from NSF through the MRSEC program. The highlighted project was presented at the “IUPAC MACRO2012 World Polymer Congress” in Blacksburg and the “International Conference on Science and Technology of Synthetic Metals 2012” in Atlanta. Significantly, the graduate student associated with this project was selected as a finalist in the 2012 AkzoNobel Student Award Symposium to be held during the ACS 2012 Fall National Meeting, in Philadelphia.
