Sum Frequency Generation Imaging Microscopy of Patterned Self-Assembled Monolayers with Terminal #CH

Ultrafast vibrational dynamics and spectroscopy of a siloxane self-assembled monolayer.

Time and frequency domain sum-frequency generation (SFG) were combined to study the dynamics and structure of self-assembled monolayers (SAMs) on a fused silica surface. SFG-free induction decay (SFG-FID) of octadecylsilane SAM in the CH stretching region shows a relatively long time scale oscillation that reveals that six vibrational modes are involved in the response of the system. Five of th...

Scanning Force Microscopies Can Image Patterned Self-Assembled Monolayers

This paper demonstrates that scanning probe microscopies (SPMs) can image patterned self-assembled monolayers (SAMs) formed by microcontact printing. Lateral force microscopy (LFM) and force modulation microscopy (FMM) showed contrast between regions of patterned SAMs terminated by different chemical functionalities. Normal force microscopy (NFM) typically showed less contrast than LFM or FMM b...

Phase decomposition in polymer blend "lms cast on substrates patterned with self-assembled monolayers

Thin polymer "lms with lateral structures are expected to play an important role in future applications (e.g. plastic-based electronic devices). Such structures could be formed when blend "lms are spun-cast onto substrates patterned with self-assembled monolayers (SAM). The spin-coating process results in composition variations accompanied by surface undulations. We have studied both phenomena ...

Probing the Molecular Conformation of Self-Assembled Monolayers at Metal/Semiconductor Interfaces by Vibrational Sum Frequency Generation Spectroscopy

Patterned crystallisation on self-assembled monolayers with integrated regions of disorder†

This paper describes the engineering of patterned calcite films using templating by self-assembled monolayers (SAMs) supported on micropatterned mixed metal substrates. The substrates were prepared by deposition of one metal (Au, Ag) onto the surface of another metal (Au, Ag) through a stencil or photoresist masks. The micropatterning arises from the generation of disordered regions in SAMs at ...
