Influence of specific intermolecular interactions on the self-assembly and phase behavior of oligo(ethylene glycol)-terminated alkanethiolates on gold
Article Abstract:
A comparative study of the self-assembly and phase behavior of seven different oligo(ethylene glycol) (OEG)-terminated alkanethiols on polycrystalline gold surfaces is presented. The results from contact angle goniometry, null ellipsometry, and infrared reflection, absorption spectroscopy (IRAS) indicate that the intermolecular interactions can be partly used to control the conformation and order of the OEG portion of the self-assembled monolayers (SAMs).

Ice nucleanation and phase behavior on oligo(ethylene glycol) and hydroxyl self-assembled monolayers: Simulations and experiments
Article Abstract:
The nucleation and phase behavior of ultrathin D(sub 2)O-ice overlayers were studied on oligo(ethylene glycol) (OEG)-terminated and hydroxyl self-assembled monolayers (SAMs) at low temperature in ultrahigh vacuum. The results revealed a difference in kinetics, which is most likely due to the pronounced D(sub2)O interpenetration and binding to all-trans segments of the ethylene glycol portion of the SAM.

Temperature-driven phase transitions in oligo(ethylene glycol)-terminated self-assembled monolayers
Article Abstract:
The phase behavior of oligo(ethylene glycol) self assembled monolayers using temperature programmed infrared reflection adsorption spectroscopy are explored. The oligomer conformation is marginally affected upon increasing the temperature to 75 degree Celsius, displaying the dominating all-trans phase.
