ACS Applied Materials & Interfaces 3 (6): 1809-1812 (2011)

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 × 102 and 1 × 104 Ω m and the growth direction can be controlled as well by using a prestructured substrate.
