In this paper,the core-expanded benzene derivative (6 CNTM)bearing two 2-(1 ,3-dithiol-2-yli-dene)malonitrile group at the central benzene core are designed and synthesized.Here,their optical and electro-chemical properties were investigated by UV -Vis absorption and cyclic voltammetry .Importantly,the charge transport properties of thin film OFET based-on 6CNTMwere stuied for the first time.Thin film OFETs shows e-lectron transport performance (μe=6.6 ×10 -3cm2/V·s,Vth =14V and Ion/Ioff=4 ×102).This result com-fimed acenes modified by two moieties are promising high-performance,ambient-stable n-type organic semi-conductors.%通过在苯环中心引入两个2－（1，3－二巯基－2－亚基）丙二腈基团，设计合成了苯环扩展的衍生物6 CNTM。通过紫外－可见吸收和循环伏安法研究其光学和电化学性质；首次研究了基于材料6 CNTM的薄膜OFET的电荷传输性质。结果显示：薄膜OFET器件具有电子传输性能，电子迁移率为6．62×10－3cm2／V·s，阈值电压（Vth）为14V，开关比（Ion／Iof）为4×102。为将此基团引入并苯化合物中，设计合成高性能、空气中稳定的n－型有机半导体材料提供前瞻性指导。
