An ultralong single organic semiconducting nano/microwire (NMW) is difficult to obtain. Here we show that this NMW can easily be prepared by using drying under solvent atmosphere method. This technique is not only unique, but also very compatible with our active material, spiro-substituted perylenetetracarboxylic diimide. A single NMW with a length of up to ∼5.5 mm and an aspect ratio of ∼9200 can be obtained. Finally, we succeeded to measure the electrical resistivity of a single NMW with values between 1 × 10(2) and 1 × 10(4) Ω m and the growth direction can be controlled as well by using a prestructured substrate.
获得超长的单个有机半导体纳/微米线（NMW）非常困难。在这里，我们展示了一种通过在溶剂气氛下干燥的方法可以很容易地制备这种 NMW。这种技术不仅独特，而且与我们的活性材料，螺取代苝四羧酸二酰亚胺非常兼容。可以获得长度高达约 5.5 毫米且纵横比高达约 9200 的单个 NMW。最后，我们成功地测量了单个 NMW 的电阻率，其值在 1×10(2)和 1×10(4)Ωm 之间，并且通过使用预结构化衬底可以控制生长方向。
