Facile synthesis of [Cu(SCH3)]∞ nanowires with high charge mobility

[Cu(SCH₃)]_∞ nanowires with lengths on the order of hundreds of micrometers were obtained with a facile method from the reaction of Cu(NO₃)₂·3 H₂O, dimethyl sulfoxide (DMSO), and water under hydrothermal conditions within a large range of DMSO/water ratios and at various temperatures. These highly crystalline, thermally stable (under vacuum) nanowires are p-type conducting and have a hole mobility as high as 2 cm² V^-1 S^-1, which is 10²-10⁵ times higher than previously reported values. The high hole mobility may demonstrate their promising future in various electronic-device applications. On the wire: Highly crystalline, superlong [Cu(SCH₃)]_∞ nanowires, obtained from the hydrothermal reaction of Cu(NO₃)₂·3 H₂O, DMSO, and water, display a high hole mobility of 2 cm² V ^-1 S^-1 (see figure), which demonstrates their promising future in electronic-device applications.
