Polymorphism in Self-Assembled Terphenylthiolate Monolayers on Au(111)

“…The formation of stable, well-ordered, and densely packed self-assembled monolayers (SAMs) on solid surfaces has become the focus of broad academic interest. − The wide attention attracted by SAMs is due to the large diversity of existing and potential applications in a variety of fields such as antifouling, , biosensorics, − electrochemistry, , and lithography. − Still, the majority of SAM studies are performed on alkanethiol-based SAMs on Au(111), which can be easily prepared by immersion of the substrates into solutions of the corresponding thiol. , Recently, SAMs of conjugated molecules became very popular due to their potential applications in molecular electronics , and electronic interfaces. , In previous studies, it has been found that the precise structural arrangement within the SAMs of conjugated aromatic thiolates depends critically on a complicated balance of contributions such as intermolecular interactions and anchor–substrate bonding. − The rational design of such monolayers requires specific knowledge of these factors and their relative importance. Therefore, several studies have been carried out to understand the structure and kinetics of film formation of conjugated aromatic thiols on gold surfaces. − Since biphenyl (BP) and terphenyl (TP) based thiolate SAMs are representative of conjugated SAMs, the high coverage phases of these SAMs have been examined in considerable detail using various spectroscopic and microscopic techniques. ,,− ,− Just recently, two groups independently reported on the structure of the monolayers of the unsubstituted biphenylthiol (BPT). , Kang et al reported the formation of a well-ordered (√3 × √3) R 30° structure on Au(111) from ethanol at 60 °C after short deposition times . This structure was overlaid by a stripe pattern ...…”

Switchable cholesterol recognition system with Diels–Alder reaction using molecular imprinting technique on self‐assembled monolayer

“…Our research group has tried to conduct molecular imprinting with a self‐assembled monolayer (SAM) on a gold plate as an extreme surface molecular imprinting. Our results revealed that the electrode in our system exhibited molecular recognition ability . We called this method two‐dimensional molecular imprinting.…”
