Abstract We have fabricated polycrystalline thin film transistors (TFTs) with a liquid crystalline material i.e., dihexylquaterthipohene by solution process. The TFTs exhibited p-channel performance and its mobility was determined to be 0.04cm2/Vs, which was comparable to that determined by time-of-flight experiments. We discuss that how ‘‘liquid crystallinity’’ helps fabricating uniform thin films on substrates by spin-coating and controlling grain boundaries not to across the conduction channels formed by self-aligned p-conjugated aromatic cores in liquid crystalline molecules, and conclude that liquid crystalline material is a good candidate for quality polycrystalline thin films for organic TFTs.
