Abstract:
1,6-Hexandithiol (HDT) forms 6.9 +/- 1.0 A thick defect-free monolayers on gold substrates if the solution is purged by argon during the adsorption while long term (> 1000 min) exposure of the substrate to alcoholic HDT results in the stepwise formation of multilayers in the absence of argon purging.
