Novel butterfly pyrene-based organic semiconductors for field effect transistors

Abstract
Novel butterfly pyrene derivatives functionalized with trifluoromethylphenyl and thienyl aromatic groups in the 1-, 3-, 6- and 8-positions of pyrene cores 1 and 2 have been synthesized by Suzuki coupling reactions, and their crystal structures, optical and electrochemical properties investigated; additionally, the field effect transistor using 2 as the active material exhibited a p-type performance.
