Dithiocarbamate-Based Self-Assembled Monolayers - The Preparation Method Has a Crucial Impact on Structure and Stability.

ABSTRACT: Dithiocarbamates (DTCs) are a promising group of molecules where a bidentate bonding group is used to functionalize metallic surfaces as self-assembled monolayers (SAMs). So far, two methods of DTC SAMs deposition have been employed interchangeably: in situ generation of a DTC compound or synthesis of a salt precursor that can then be used on demand. Here, using the two model DTC SAMs based on phenylpiperidine and phenylpiperazine, we compare for the first time these two synthetic approaches in one study. We show that for the crucial parameters of monolayers, such as packing density and thermal stability, there is a significant difference between the two formation methods, promoting the in situ one, which produces monolayers with high thermal stability (desorption ener
