Printable Electronics: From Living Synthesis of Conducting Polymers to High Mobility Transistors

Regioregular, head-to-tail coupled, block copolymers of thiophenes and other polymers can drive a self-assembly in polythiophenes at the nanoscale through polymer phase-separation. These new polymers have allowed us to create not only highly conductive polymers, but also printable transistors with high mobilities. Living synthesis of regioregular polythiophenes has been discovered through new mechanistic insights to the reaction chemistry, that ultimately leads to enhanced device performance. New FET materials and design constraints for optimization of organic FETs will be discussed.
