✦ Synopsis
molecules on the substrate or with other molecules in the New polyamides containing disulfide bonds in their main chains solution. Therefore, the polymers may provide multifuncare prepared by condensation between 3,3-dithiodipropionic acid tionalized surfaces with easy preparation. and various alkyldiamines (NH 2 -(CH 2 ) n -NH 2 , n Å 4 and 12, poly-In this paper we describe the preparation and adsorption amide I and II). The polyamides form a thin layer on a gold of new types of polyamides which contain disulfide bonds substrate. The surface of polyamide modified electrodes were inin their main chains. Furthermore, the adsorption behavior vestigated by AFM and XPS measurements. The surface structure of ferrocene derivatives on the polyamide modified surface depends on the polyamide structure, especially alkyl chain length is also investigated. The ferrocene derivatives are 1-ferrocenof the polyamide. Furthermore, adsorption of ferrocene derivatives ylmethanol (FME) and 2-amino-3-ferrocenylpropionic acid [1-ferrocenylmethanol (FME) or 2-amino-3-ferrocenylpropionic acid (AFP)] on the polyamide modified electrodes and their elec-(AFP), which have interactive functional groups with amide trochemical responses were investigated. Interaction between the bonds. Amide bonds in the polymer chain will act as interpolyamide on the electrode and the ferrocene derivatives depends active sites with hydroxyl, carbonyl, or amino groups in on the structure of the ferrocene derivatives and polyamide chain the ferrocene derivatives through the formation of hydrogen length. ᭧ 1997 Academic Press bonds.
