We show that elastomeric surfaces can be tailored using "mechanically assembled monolayers" (MAMs), structures that are fabricated by combining self-assembly of surface grafting molecules with mechanical manipulation of the grafting points in the underlying elastic surface. The versatility of this surface modification method is demonstrated by fabricating MAMs with semifluorinated (SF) molecule...

Binary and ternary self-assembled monolayers (SAMs) adsorbed on gold nanoparticles (NPs) have been previously studied for their propensity to form novel and unexpected patterns. The patterns found were shown to arise from a competition between immiscibilty of unlike surfactants and entropic gains due to length or other architectural differences between them. We investigate patterns self-assembl...

We demonstrate that colloidal lithography with self-assembled monolayers of crosslinkable polymeric particles can be used to create hierarchical arrays of nanopores on substrates.

Ultrathin (submicrometer) organic films of specified index of refraction are constructed by the sequential deposition of self-assembled zirconium phosphonate (ZP) molecular monolayers that contain two Merent bisphosphonate ions, 1,lO-decanediylbis(phosphonate) (DBP) and 4,4azobis[(p-phenylene)methylenelbis(phosphonate) (AZO). By varying the ratio of DBP to AZO monolayers in the ZP multilayer fi...

Recent advances in the field of self-assembly have led to the development of a plethora of new technologies based on soft lithography (see Self-assembled Monolayer Films: Microcontact Printing; Thiol-based Selfassembled Monolayers: Formation and Organization; Thiol-based Self-assembled monolayers, Structure of) that enable alternative ways of creating twoand three-dimensional chemical patterns ...

Self-assembled monolayers are a ubiquitous laboratory tool and have been the subject of many experimental investigations which have primarily focused on static properties of full coverage monolayers, with the maximum density and ordering possible. In this work, dynamics within low density, planar siloxane self-assembled monolayers are studied utilizing highly sensitive dielectric spectroscopy. ...

Aryldiazonium-terminated methylene-spaced trifluoromethylazobenzene derivatives have been synthesized. Their self-assembled monolayers (SAMs) on a silicon surface allow for a stable and reversible molecular photoswitch.
