| Abstract
| - 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 baseformation with poly(allylamine). Direct evidence for imine formation was obtained from X-ray photoelectron spectroscopyand from attenuated total reflection IR spectroscopy. These modified surfaces could be removed from the aqueoussubphase into air with retention of the assembly and its orientation relative to the surface, as evidenced by atomicforce microscopy, water contact angle measurements, and film thickness determinations by ellipsometry. Similarassemblies were also synthesized via a postgluing procedure, in which the substrate containing the LB monolayerwas removed from the subphase and rapidly immersed into an aqueous solution containing poly(allylamine). Thepotential of combining postgluing methods with continuous LB film deposition as a surface modification techniqueis briefly discussed.
