“…One of the most compelling advantages of lDP compared to conventional microcontact printing is the ability to pattern molecules with low intermolecular interaction strengths, where the AD SAM prevents lateral diffusion of the patterned adsorbates both during and after patterning [6,46]. When regions of a chemical pattern are selectively desorbed, if the remaining adsorbates do not have sufficient intermolecular interaction strengths, they will tend to diffuse across the surface, resulting in pattern degradation.…”

“…Weiss and coworkers used 1-decanethiol and 11-mercaptoundecanoic acid to replace 1-adamantanethiol from the gold surface during mCP with a PDMS stamp. [51,52] The extent of displacement during the printing of micrometer-wide features was controlled by tuning the ink concentration and contact time. The original 1-adamantanethiolate SAM hinders the lateral surface spreading of the ink molecules from the stamp.…”

Microcontact printing (µCP) offers a simple and low‐cost surface patterning methodology with high versatility and sub‐micrometer accuracy. The process has undergone a spectacular evolution since its invention, improving its capability to form sub‐100 nm SAM patterns of various polar and apolar materials and biomolecules over macroscopic areas. Diverse development lines of µCP are discussed in this work detailing various printing strategies. New printing schemes with improved stamp materials render µCP a reproducible surface‐patterning technique with an increased pattern resolution. New stamp materials and PDMS surface‐treatment methods allow the use of polar molecules as inks. Flat elastomeric surfaces and low‐diffusive inks push the feature sizes to the nanometer range. Chemical and supramolecular interactions between the ink and the substrate increase the applicability of the µCP process.

“…Self-assembled monolayers of adamantane-1-thiol, the smallest, most abundant, and most readily synthesized diamondoid, forms highly packed hexagonal layers on Au(111) reportedly with lower defect densities than alkane thiols, with a 7x7 reconstruction and 6.9 Å nearest neighbor distance [21][22][23] . These adamantanethiol monolayers are also readily displaced by alkane thiols 22,23 , a useful property for nanolithography [22][23][24][25] . This labile behavior is attributed to the bulky nature of the adamantane which may impose steric restrictions that induce non-optimal Au-S bonding 23 .…”

Diamondoids, hydrocarbon molecules with cubic-diamond-cage structures, have unique properties with potential value for nanotechnology. The availability and ability to selectively functionalize this special class of nanodiamond materials opens new possibilities for surface-modification, for high-efficiency field emitters in molecular electronics, as seed crystals for diamond growth, or as robust mechanical coatings. The properties of self-assembled monolayers (SAMs) of diamondoids are thus of fundamental interest for a variety of emerging applications. This paper presents the effects of thiol substitution position and polymantane order on diamondoid SAMs on gold using nearedge X-ray absorption fine structure spectroscopy (NEXAFS) and X-ray photoelectron spectroscopy (XPS). A framework to determine both molecular tilt and twist through NEXAFS is presented and reveals highly ordered diamondoid SAMs, with the molecular orientation controlled by the thiol location. C 1s and S 2p binding energies are lower in adamantane thiol than alkane thiols on gold by 0.67 ± 0.05 eV and 0.16 ± 0.04 eV respectively. These binding energies vary with diamondoid monolayer structure and thiol substitution position, consistent with different amounts of steric strain and electronic interaction with the substrate. This work demonstrates control over the assembly, in particular the orientational and electronic structure, providing a flexible design of surface properties with this exciting new class of diamond clusters.3
