Micron-Scale Patterning of Conjugated Polymers on Microcontact Printed Patterns of Self-Assembled Monolayers

Self-assembled monolayers of alkanethiols on gold inhibit the electrooxidative deposition of polypyrrole and polyaniline. Oxidation of aniline at an electrode modified with μm-scale regions of ethanethiol and 12-aminododecanethiol results in selective deposition of polyaniline on the hydrophobic short chain alkanethiol.
