LB-Deposited, Side-Chain Substituted Polyaniline, Polypyrrole and the Corresponding Monomers, Studied by STM
Abstract
STM investigations were carried out on monolayers of two conducting polymers and the corresponding monomers. 2-pentadecyl-aniline, poly-2- pentadecyl-aniline, 3-hexadecyl-pyrrole and poly-3-hexadecyl-pyrrole which were transferred from the liquid/air interface on a MoS2 substrate by the Langmuir- Blodgett technique. The polymers were polymerized at the liquid/air interface with ammonium persulfate in the sub phase as the oxidizing agent. All compounds showed high orientational and positional order on the substrate surface. Two different structures were observable, rows and rod like structures. The distance between the rods were found for all compounds =4.3A. The row distances were found to be different for every substance. We think that the rods are the alkyl side chains and the rows represent the polymer chain or molecular monomer aggregates.
