Abstract:

A two-dimensional conducting polyaniline (PAN) monolayer has been formed on an elec. insulating monolayer. The approach is based on the electrochem. polymn. of surface-confined anilinium ions that were electrostatically attached to a neg. charged self-assembled monolayer of ω-mercaptodecanesulfonate (MDS), HS(CH2)10SO3-, on a gold surface. The formation and characterization of the two-dimensional film and the MDS monolayer have been examd. by cyclic voltammetry, Fourier transform IR spectroscopy, XPS, wettability, and scanning electrochem. microscope. The formation of a capacitor-like assembly, in which electron transfer was blocked between PAN and the gold surface, was accomplished by electrochem. incorporating hexadecanethiol (C16) into the MDS monolayer. The PAN monolayer exhibits properties similar to those of a thin polymer film. [on SciFinder(R)]
