Self-organization of gold nanoparticles on surface-modified conducting polymer films
Thiol-coated gold nanoparticles with a diameter of approximately 7.5 nanometers and a narrow particle distribution were prepared from sodium tetrachloroaurate under phase transfer conditions. The thiols used were 1-mercaptododecane (1) and 1-mercapto-9,11-heptadecadiyne (4). The particles were cast onto thin films of polyaniline and poly(3,4-ethylenedioxythiophene), as well as onto thiol-coated versions of the same polymer. Surface modification of the polymers with long chain thiols encourages the spontaneous self-assembly of the particles into two-dimensional arrays and may offer a unique method for stabilization of nanoparticle assemblies on polymer substrates.
