英文摘要	Dicyanomethylene-substituted quinoidal dithieno [2,3-d;2',3'-dlbenzo [1,2-b;4,5-b1 dithiophene compounds (QDTBDTs) with alkyl chains branched at different positions were synthesized. Thin-film transistor characteristics showed that the type of charge carriers in QDTBDTs could be tuned by changing the branching position of the alkyl chains. QDTBDT-2C exhibited n-channel behavior, and the observed electron mobility was 0.57 cm(2) V-1 s(-1) without post-treatment, one of the highest values reported for spin-coated thin-film transistors with no annealing under ambient conditions. QDTBDT-4C-based transistors displayed electron-dominated ambipolar transport behavior, with electron mobilities reaching 0.2 cm(2) V-1 s-i and hole mobilities in the range of 10-3-10-4 cm(2) V-1 s(-1). QDTBDT-3C showed solution-concentrationdependent carrier transport characteristics, exhibiting n-type behavior at low solution concentrations and ambipolar performance at high solution concentrations with an electron mobility of 0.22 cm(2) V-1 s(-1) and a hole mobility of 0.034 cm(2) V-1 s(-1). CMOSlike inverters fabricated from QDTBDT-2C displayed high gain and high noise margins.
