“…A small residual surface pressure that was apparent after these expansion/compression cycles is presumed to be due to trace amounts of polymeric surfactant remaining on the Wilhelmy plate used for recording surface pressures. Similar behavior has previously been reported for compressed monolayers of 1-octadecanal over a subphase containing poly( l -lysine) . Control experiments that were carried out in the absence of 2 over a similar aqueous PAA subphase showed no detectable surface pressure.…”

Langmuir-Blodgett (LB) monolayers of 5,11,17,23,29,35-hexaformyl-37,38,39,40,41,42-hexakis(1-n-octyloxy)calix[6]arene (2), deposited onto silylated silicon wafers, were cross-linked (i.e., "covalently glued") via Schiff base formation with poly(allylamine). Direct evidence for imine formation was obtained from X-ray photoelectron spectroscopy and from attenuated total reflection IR spectroscopy. These modified surfaces could be removed from the aqueous subphase into air with retention of the assembly and its orientation relative to the surface, as evidenced by atomic force microscopy, water contact angle measurements, and film thickness determinations by ellipsometry. Similar assemblies were also synthesized via a postgluing procedure, in which the substrate containing the LB monolayer was removed from the subphase and rapidly immersed into an aqueous solution containing poly(allylamine). The potential of combining postgluing methods with continuous LB film deposition as a surface modification technique is briefly discussed.

“…Ni-Al Alfa-Ventron), and analytical grade inorganic reagents were used. 4,4'-Dimethyl-2,2'-bipyridine (G. Frederick Smith) was oxidized to 2,2'-bipyridyl-4,4'-dicarboxylic acid and esterified to the diethyl ester by published methods.8 c«-Dichlorobis(2,2'-bipyridine)ruthenium(II)7 and cw-dicyanobis(2,2'-bipyridine)ruthenium(II), 6,13 were also synthesized according to literature procedures. Reactions were done under a nitrogen atmosphere (purified by passing N2 through activated beds of Ridox and calcium sulfate).…”
