The monolayer of amphiphilic Cu(NO3)(2)(dps), (2,2'-dipyridylstearylamine)d
initratocopper (II). was studied at the air-water interface. Cu(NO3)(2)(dps
) was synthesized from substitution of stearyl chloride with dipyridylamine
followed by coordination of the ligand with Cu(NO3)(2). 3H(2)O. The Cu(NO3
)(2)(dps) monolayer was stable up to ca. 20 mN/m of surface pressure and sh
owed condensed phase. The surface pressure-area isotherms were exactly repr
oducible from the second compression-expansion cycle. The optical image of
the monolayer was monitored by Brewster angle microscopy (BAM). Homogeneous
monolayer phase was estimated from the BAM images. The Cu(NO3)(2)(dps) mon
olayer was transferred on calcium fluoride substrate as Y-type and the chem
ical structure of the Langmuir-Blodgett film was determined by FT-IR spectr
oscopy. (C) 2001 Elsevier Science B.V. All rights reserved.
