Sessile drop contact angle measurements demonstrate the hydrophobic nature of these self-assembled thin films. The thicknesses of the films as measured by optical ellipsometry correspond well to the calculated thickness of monolayer films in which the extended alkyl chains are oriented at a 30° angle to the Au surface. The films are densely packed and are passivating to electron transfer between the Au surface and K4Fe(CN)6 in a contacting aqueous KCl solution. Grazing angle reflectance FTIR spectra show that the aromatic fluorenyl groups are fixed at a defined distance from the Au surface as determined by alkyl chain length disposed in an all-trans conformation. Surface fluorescence spectra for the SAMs are red-shifted and broadened compared with the corresponding molecule's fluorescence when measured in dilute solution.
