The present master thesis focuses on the use of a novel bolaamphiphilic hexayne as a molecular precursor for the formation of hybrid carbon-inorganic nanocoating. The molecule, hexadeca-3,5,7,9,11,13-hexayne-1,16-diylbis(phosphonic acid), displays a central, highly reactive oligoyne segment able to carbonize when exposed to mild UV irradiation at room temperature, while the terminal phosphonic heads lead the molecular to form a self-assembled monolayer onto oxidic surfaces. By introducing of a metallic cation, which acts as a bridging element between different organic layers, a multilayered structure can be obtained, and eventually carbonized by UV irradiation. The target molecule was obtained from 4-bromo-1-butyne, protected at first by dethylphosphonate, followed by bromination of the terminal alkyne, Negishi coupling with 1,4-bis(trimethylsilyl)butadiyne to get the asymmetric triyne, a modified Eglinton-Galbraith homocoupling that furnishes the hexayne, and finally the deprotection of the terminal phosphonates by removal of the ethyl moieties, to furnish the diphosphonic acid.
