This
article reports on a facile and fast strategy for the self-assembled
monolayer (SAM) functionalization of nickel surfaces, employing cyclic
voltammetry (CV) cycling of a suitable tailored solution containing
the species to be adsorbed. Results are presented for ultrathin films
formed on Ni by 1-hexadecanethiol (C16), l-cysteine (l-cys), and the poly{methyl (2<i>R</i>)-3-(2,2′-bithiophen-4-ylsulfanyl)-2-[(tert-butoxycarbonyl)amino]propanoate}
(PCT-L) thiophene-based chiral polymer. The effective formation of
high-quality ultrathin organic films on the nickel was verified both
electrochemically and by exploiting typical surface characterization
techniques such as contact angle, ellipsometry, atomic force microscopy
(AFM), polarization modulation–infrared reflection–absorption
spectroscopy (PM–IRRAS), and X-ray photoelectron spectroscopy
(XPS).
