Abstract
Ferrocenyl-functionalized PPI dendrimers of generations 1−5 were adsorbed at self-assembled monolayers of heptathioether-functionalized β-cyclodextrin (βCD) on gold. The dendrimers form stable supramolecular assemblies at the βCD host surface having multivalent supramolecular interactions and could be electrochemically desorbed from the surface. Using cyclic voltammetry, the stoichiometries of the dendrimers at the surface could be determined for all generations, which were quantitatively confirmed for generations 1 and 2 by surface plasmon resonance titrations.Keywords
