我们展示了一种新的基于溶液的组装方法，使用毛笔实现可控的高度取向和大规模的TCNQ单晶微丝阵列的制造。阵列不仅可以生长在传统的刚性基板上，如Si，Si/SiO2和低成本玻璃，而且还可以生长在非传统基板上，包括柔性聚对苯二甲酸乙二醇酯（PET），弯曲的玻璃半球和市售的塑料隐形眼镜。通过调节溶液浓度、衬底温度、电刷类型、电刷倾角和电刷压力来优化其形貌。微线阵列的长度可以延伸到毫米级，并且它们的优先取向垂直于刷毛的纵向方向。取向一致的微丝阵列覆盖面积可达1.5 × 2.0 mm 2，成功率高达93%。基于这些微丝阵列，可以在不同衬底上，包括刚性Si/SiO2和柔性PET，很容易实现在一个步骤。研究了TCNQ晶体在浓度控制下的各向异性输运。所有这些结果都说明了这种简便的毛笔法在大规模、高质量的有机微/纳米线的生长中具有广阔的应用前景，可用于集成到柔性有机半导体器件和电路中。
We demonstrate a novel solution-based assembly method using a writing brush to realize the controllable fabrication of highly-oriented and large-scale TCNQ single-crystal microwire arrays. The arrays can not only be grown on conventional rigid substrates, such as Si, Si/SiO2 and low-cost glass, but also on nonconventional substrates, which include flexible polyethylene terephthalate (PET), curved glass hemispheres and commercially available plastic contact lenses. Their morphology is optimized by tuning solution concentration, substrate temperature, brush type, inclination angles and pressure of the brush. The length of the microwire arrays can extend to the millimeter level, and their preferential orientation is perpendicular to the lengthwise direction of the brush hair. The coverage area of microwire arrays with a consistent orientation can reach 1.5 × 2.0 mm2 and the success ratio is as high as 93%. Based on these microwire arrays, devices on different substrates, including rigid Si/SiO2 and flexible PET, can be easily realized in one step. The anisotropic transport of TCNQ crystals is studied with respect to the concentration controlled morphology. All these results illustrate the broad application prospects of this facile writing-brush method in the growth of large-scale, high-quality organic micro/nanowires for integration into flexible organic semiconductor devices and circuits.
