摘要
The preparation and characterization of self-assembly organic multilayer films on hydroxylated silica (SiO2) surface are reported. The multilayer films, constructed via Si-O cross-links and Schiff base reactions alternately, are characterized by advancing-contact-angle measurement, grazing-incidence IR spectroscopy and X-ray photoelectron spectroscopy. The results indicate that both Si-O bonding and Schiff base reactions at the solid/liquid interface, on the employed strict experiment condition, are successful. The superlattice multilayer films have an ABAB...stacking sequence and good structural regularity. The aromatic moiety is interlocked between two short alkyl chains and perpendicular to the surface.
