Deposition of polyaniline on micro-contact printed self-assembled monolayersof ω-functionalized alkanethiols

Abstract

Electrooxidative polymerization of aniline on electrodes modified with microcontract printed self-assembled monolayers of 12-aminododecane-1-thiol and alkanethiols allows for facile production of micron-scale patterns of polyaniline whereas patterns of two alkanethiols do not allow for selective deposition. The effect of terminal functionality on the interfacial properties of monolayers must be considered in addition to the length of the alkyl chain in the selection of adsorbates for spatially resolved electrochemical polymerization.
