Abstract
The electrodeposition and properties of poly(1,8-diaminonaphthalene) f ilms on Au electrodes have been studied using electrochemical quartz c rystal microbalance and crystal impedance measurements. Redox switchin g of films exposed to aqueous 0.1 mol dm(-3) HClO4 is accompanied by n on-monotonic mass changes: proton, counter-ion and solvent transfers o ccur to extents dependent upon the experimental timescale. The films a re also able to extract Hg2+ ions from solution, via complexation with amine groups on the polymer. Coulometric and gravimetric data are con sistent with a 1:1 mercury:amine complexation stoichiometry.
