Mh. Dishner et al., FORMATION AND PHOTOOXIDATION OF N-DODECANETHIOL SELF-ASSEMBLED MONOLAYERS ON AU(111) - PITS FORMED DURING CHEMISORPTION DISAPPEAR UPON OXIDATION, Chemical communications, (16), 1996, pp. 1971-1972
UV photolysis in air of self-assembled n-dodecanethiol monolayers (SAM
s) on Au(111) quantitatively oxidizes the adsorbed thiol to its corres
ponding sulfonate and completely destroys the ordered structure of the
SAM without exposing the underlying gold surface; STM images indicate
that the etch pits which appear to form during chemisorption of the t
hiol are lost when the thiol is oxidized.
