摘 要：Fabricating n-type organic thin film transistors(OTFTs)based on small molecules via solution processing under atmospheric conditions remains *** small molecules with polymer is an effective strategy to improve the solution processibility and air stability of the resulted *** this study,polystyrene was chosen to blend with n-type small molecule DPP1012-4F to enhance the continuity of the semiconductor layer and maintain a favorable edge-on stacking of *** introduction of high-boiling point 1-chloronaphthalene as a solvent additive in the blending system can reduce the grain boundary defects in the microscopic *** changes in aggregation behavior are confirmed by X-ray diffraction,atomic force microscopy and polarized optical microscopy *** bar-coating of the semiconductor layers in air,the electron mobility of the resulted OTFTs under the optimal condition is 0.73 cm2·V–1·s–1,which is amongst the highest n-type small molecule-based OTFTs with active layers prepared in air up to *** results show a great potential of the blending strategy in industrial roll-to-roll manufacture of high-mobility n-type OTFTs.
