Yt. Tao et al., EFFECT OF BIPHENYL AND NAPHTHYL GROUPS ON THE STRUCTURE OF SELF-ASSEMBLED MONOLAYERS - PACKING, ORIENTATION, AND WETTING PROPERTIES, Journal of the American Chemical Society, 115(21), 1993, pp. 9547-9555
The self-assembling behavior of a series of 4-alkoxybiphenyl-4'-carbox
ylic acid and 6-alkoxy-2-naphthoic acid compounds on the surfaces of A
g and Cu was studied. The structure of the monolayer film was probed w
ith ellipsometry, reflection absorption IR spectroscopy, and contact a
ngle measurements. The effect of aromatic chromophores on the packing,
orientation of the molecular assembly, and wetting properties of the
monolayer film was investigated. These monolayer structures were compa
red with those of n-alkanoic acids and n-alkanethiols to deduce the pa
cking mechanism of carboxylic acid adsorption on metal oxides.
