Long‐Range Molecular Organization of an Organic Monolayer Grafted on a Mineral Substrate

Abstract

Structured and functional materials are of the utmost importance for the development of microelectronic technology. We report on a method to obtain a highly ordered organic molecular layer on a mineral substrate. We took advantage of the regular array of reactive sites present at the single-crystal surface of topaz to perform a liquid-phase silanization reaction. The grazing-incidence diffraction technique was used to characterize the bare and covalently coated surfaces. The ordering of the monomolecular organic layer reproduces the perfect single-crystal structure of the cleaved surface over millimeter distances.

Supramolecular Electrostatic Nanoassemblies for Bacterial Forensics

“…These interfacial OH groups were used to bind an alkane monolayer by a silanization reaction (Figure 6). The present preparation of a perfectly ordered monomolecular brush of organic molecules is a promising result24 that should open new routes to functionalized materials, for example, in the design of organic transistors. The insulator material (e.g.…”

Metastability and Sol Phases: Two Keys for the Future of Molecular Gels?

“…Also, controlling the correlation of position and orientation is crucial for encoding original functions and properties. Such an objective can be envisioned at molecular-scale resolution for covalent epitaxial grafting, 32 and the challenge is now to approach the nanoscale with functional rods. An investigation of the structures developed by the gelator at the air-water interface in a Langmuir trough at various surface pressures is an interesting and preliminary step in identifying the morphs and molecular packing modes available to the gelator.…”

Extended Surfaces Nanopatterned with Functionalized Cavities for Positioning Nanoparticles

“…Such interest is driven by multiple potential applications in catalysis, sensing, optoelectronics, magnetism, etc. Various options have been explored to develop such surfaces: electron beam lithography, nanoimprint methods, focused ion beam techniques, , or nanopatterning based on polymer self-assembly. , These strategies complete the molecular approach consisting of epitaxial and covalent grafting of molecules on crystallographically suitable solid substrates . A challenging objective remains the obtaining of nanostructured surfaces with functionalizable nanosites organized over macroscopic distances.…”
