Abstract
Three naphthalene diimides (2, 3 and 4) fused with 2-(1,3-dithiol-2-ylidene)-2-fluorophenylacetonitrile moieties were designed and synthesized. Due to the different substituted positions of fluorine atom on the phenyl group, the solution-processed thin films of 2 and 3 operated in air as n-channel transistors, while the films of 4 performed as ambipolar transistors, indicating that the variation of substituted position of fluorine atom on molecular backbone may tune the material's charge transport behavior.
