title: 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.
