Differences in the Self-Assembly of Thiol and Disulfide Derivatives of Viologenson Au

摘要

A direct comparison of the self-assembly on Au of thiol and disulfide derivativesof viologens bearing long n-alkyl chains was made in order to ascertain the relative efficiency of monolayer formation for each type of functionality. The structures the two derivatives which were studied can be written as CH3V(2+)(CH2)12SH and CH3V(2+)(CH2)l2S2 for the thiol and disulfide,
