Tetracene and its relative, 5,6,11,12-tetraphenyltetracene (rubrene), have attracted a tremendous amount of interest as p-type crystalline organic semiconductors. Rubrene in particular possesses many of the desired qualities for an “ideal” organic semiconductor: high charge mobility (~ 20 V/m•sec in single crystals), excellent HOMO/LUMO overlap in crystalline pi-stacks, oxygen stability, solution or vapor processing, flexible thin films, and facile synthesis. This talk will focus on the design of a versatile synthesis of rubrene analogs, including crystal engineering. Characterazation of the materials, including preliminary device studies will also be presented.
Chris Douglas became an Assistant Professor at the University of Minnesota Twin Cities (Chemistry) in 2007. His interests include synthetic organic chemistry and organic semiconductors.
