A new donor molecule 3,8-dimethoxy-[1]benzothieno[3,2-b][1]benzothiophene (DMeO-BTBT) is synthesized and the charge-transfer complexes with fluorinated 7,7,8,8-tetracyanoquinodimethane (Fn-TCNQ; n = 0, 2, and 4) are prepared. All complexes (DMeO-BTBT)(Fn-TCNQ) have mixed stack structures, and the thin-film and single-crystal organic transistors show n-channel transistor performance both in vacuum and in air even after one-year storage. Although the performance and stability of the thin-film… Expand
