Paper Abstract

Self-assembled monolayers of the bidentate ferrocene containing ligands diisocyanoferrocene (1), bis(diphenylphosphanyl) ferrocene (2), and diisothiocyanatoferrocene (3) have been prepared and their adsorption kinetics on gold films were characterized with optical second-harmonic generation and ellipsometry. As opposed to ferrocenylfunctionalized ligands used in earlier studies, the redox-active moieties discussed here carry two anchor groups to "pin" them to the substrate in a well-defined orientation and distance to the surface. 1 and 3 show monolayer film formation that follows first order, while film assembly of 2 is best described by a second order Langmuir kinetics.
