Synthetic and Processing Strategies to New Molecular and Polymeric...

Recent achievements in the design and synthesis of new arene/heteroaromatic oligomers/molecules functionalized with a variety of phenacyl, alkylcarbonyl, and perfluoroalkylcarbonyl will be presented. These organic semiconductors exhibit low-lying LUMOs allowing efficient electron injection/transport. Organic field-effect transistors (OFETs) fabricated by conventional methods exhibit electron mobilities as high as 2 cm^2 V^-1 s^-1 for vapor-deposited films and 0.25 cm^2 V^-1 s^-1 for solution-cast films with current modulation > 10^8 [1]. Furthermore, these materials are compatible with new classes of nanoscopic layer-by-layer self-assembled multilayers (SAMT) and crosslinked polymeric blend (CPB) gate dielectrics developed in our group. The new dielectric materials are fabricated... Show More
