Fluorine-substituted quinoidal thiophene with a F-H hydrogen bond locked conformation for high-performance n-channel organic transistors

The novel dicyanomethylene-substituted 1,2-bis(thieno[3,2- b ]thiophene-2-yl)ethene based quinoidal compounds QBTTE and F2-QBTTE are reported. The F H (vinylene) hydrogen bonds lock the backbone conformation and greatly improve the transistor performance of F2-QBTTE . The novel dicyanomethylene-subs...
