Solution-processible n-channel organic field-effect transistors based on dicyanomethylene-substituted terthienoquinoid derivative

A new hybrid-type dicyanomethylene-substituted terthienoquinoid compound as a highly soluble n-channel organic semiconductor was synthesized, and its spin-coated thin film was utilized as an active semiconducting channel in field-effect transistors, which showed electron mobilities of up to 0.16 cm(2) V-1 S-1.
