Trapping of V(benzene)2 sandwich clusters in a n-alkanethiol self-assembled monolayer matrix
TLDR
In this article, the thermal chemistry of the neutralized sandwich cluster cations on each substrate was studied with temperature programmed desorption (TPDP) and it was determined that the activation energies of the deposited clusters are incorporated into the SAM matrix and firmly trapped inside the alkyl chains of the SAM.Abstract:
V(benzene)2 sandwich cluster cations produced in the gas phase
were size-selectively deposited onto a self-assembled monolayer of
n-hexadecanethiols (HDT-SAM) chemisorbed on a Au(111) surface as well as onto
a bare Au(111) surface. The thermal chemistry of the neutralized clusters on
each substrate was studied with temperature programmed desorption (TPD).
From the analyses of the threshold in the TPD, the desorption
activation energies of the clusters deposited were determined to be 64.4
±12.8 kJ/mol for the Au(111) and 130 ±10 kJ/mol for the HDT-SAM.
The remarkably large desorption activation energy from the SAM suggests that
the deposited clusters are incorporated into the SAM matrix and
firmly trapped inside the alkyl chains of the SAM.read more
