摘要

The fabrication of poly 3,4-ethylene dioxythiophene (PEDOT) devices generally requires a separated strategy for EDOT polymerization and PEDOT coating, thus increasing th difficulty of their integration. With the goal of insolubility of PEDOT in a common solution, material modifications including grafting vinyl moiety groups on the side chain of the PEDOT can increase its solubility, but also markedly reduce the conductivity. Here, we report direct laser writing of pure EDOT monomer into PEDOT with a feature size of 140 nm. The PEDOT nanowire possesses the high conductivity of 1.28 x 10(5) S m(-1) and can be patterned on solid and flexible substrates with various structures, thus paving the way towards organic highly conductive device fabrication and integration.
