We developed single-crystal poly(3,4-ethylenedioxythiopene) (PEDOT) nanowires with ultra-high conductivity using liquid-bridge-mediated nanotransfer printing via vapor phase polymerization. The single-crystal PEDOT nanowires are formed from ethylenedioxythiophene (EDOT) monomers that are self-assembled and crystallized during vapor phase polymerization process within nanoscale channels of a mold having FeCl3 catalysts. These PEDOT nanowires, aligned according to the pattern in the mold, are then directly transferred to specific positions on a substrate to generate a nanowire array by a direct printing process. This direct printing method in combination with vapor phase polymerization simultaneously enables the synthesis, alignment and patterning of single-crystal PEDOT nanowires. The conductivity of the single-crystal PEDOT nanowires is an average of 7619 S/cm which remarkably exceeds literature values of PEDOT nanostructures/thin films. To demonstrate usefulness of single-crystal PEDOT nanowires, we fabricated an organic nanowire field-effect transistor array contacting the ultra-high conductive PEDOT nanowires as metal electrodes.
