Abstract
Surface Science One way to stabilize self-assembly monolayers of alkane thiols on gold surfaces is to introduce amide groups into the chain near the thiol groups to form hydrogen-bonding networks. This subsurface location has made direct structural studies challenging, but Thomas et al. have used scanning tunneling microscopy and local tunneling barrier height studies of 3-mercapto- N -nonylpropionamide on Au{111} (gold films on mica) at cryogenic temperatures to map the spatial orientation of the hydrogen bond. These networks can cross the boundaries between the domains that form with different rotational orientations. ACS Nano 10.1021/acsnano.6b01717 (2016).
