The synthesis of a new series of partially fluorinated alkanethiol adsorbates of the form CH3(CF2)6(CH2)nSH (where n = 10–13), along with analysis of the resulting monolayer films on gold, are described in this presentation. The fluorinated self-assembled monolayers (FSAMs) were characterized using optical ellipsometry, polarization-modulation infrared reflection-absorption spectroscopy (PM-IRRAS), X-ray photoelectron spectroscopy (XPS), and contact angle goniometry. To shed light on the effect that the inverted HC-FC dipole has on the surface character of these partially fluorinated thin films, the wetting behavior of several contacting liquids was examined on the FSAMs and compared to that of analogous monolayers formed from CF3-terminated alkanethiols and normal alkanethiols having equivalent alkyl chain lengths. Keywords: Fluorinated Self-Assembled Monolayers (FSAMs), Odd-Even Effects, Gold, Wettability.
