Abstract
Organized organic-inorganic ultrathin films have been constructed from the fabrication of smectite unit layers and an amphiphilic ruthenium (II) complex monolayer using the conventional Langmuir-Blodgett (LB) technique. According to the method, a chloroform solution of an amphiphilic ruthenium (II) complex, [Ru (phen) 2 (dC18bpy)] 2+ (phen=1, 10-phenanthroline, dC18bpy=4, 4'-dioctadecyl-2, 2'-bipyridyl as shown in Figure. 1), was spread onto an aqueous subphase containing either exfoliated saponite or hectorite suspension. Brewster angle microscopy (BAM) observation showed that Ru (II) complex molecules formed a self-assembled monolayer on a water surface and that clay particles were adsorbed by the monolayer from an aqueous subphase. A composite film of a Ru (II) complex and a clay particle thus formed was transferred onto a hydrophilic glass plate by the vertical dipping method. The surface structure of a deposited film was studied with an atomic force microscope (AFM). As a results, a glass substrate was covered with the single sheet of a clay on which amphiphilic metal complexes were attached
