Abstract

original image

The combined application of both Langmuir–Blodgett and self-assembly techniques allows the formation of laterally structured thiolate films on gold surfaces with domains of contrasting surface properties. These monolayers with areas of amphiphilic disulfides and others of mercaptocarboxylic acids, each covalently bound, can be used for the selective formation of multilayers of copper thiol complexes (shown schematically on the right). The principle of this technique can also be applied to other fields, for example, biochemistry.
