On the complexation kinetics for metallization of organic layers: palladium onto a pyridine-terminated araliphatic thiol film.

Palladium nanoparticles have been deposited electrochemically onto self-assembled monolayers (SAMs) of 4-(4-(4-pyridyl)phenyl)phenylmethanethiol. A pronounced correlation between the kinetics of the complexation between pyridine nitrogens and Pd cations and the sample potential has been observed. The amount of the Pd deposit significantly increases by adjusting the sample potential during the complexation step to values below the point of zero charge.

Electrodeposition of Zn and Au-Zn alloys at low temperature in an ionic liquid.

In this communication, electrodeposition of Zn from 60-40 mol% ZnCl(2)-1-butyl-3-methylimidazolium chloride (BMIC) ionic liquid on Au substrates has been investigated. For the first time, initial stages of Zn electrocrystallization from BMIC has been studied by in situ X-ray diffraction (XRD) employing synchrotron radiation, which showed an initial epitaxial deposition of Zn and hexagonal Au(1.2)Zn(8.
