摘要: Mono- and multilayers of amphiphilic [Ru(phen)2(dcC12bpy)]2+ (phen = 1,10-phenanthroline, dcC12bpy 4,4‘-caboxyl-2,2‘-bipyridyl didodecyl ester) hybridized with a clay mineral have been prepared by modified Langmuir−Blodgett method, their structures properties investigated. Formation hybrid monolayer the Ru(II) complex cations platelets at an air−clay suspension interface was confirmed surface pressure−molecular area (π−A) isotherm measurement atomic force microscopic (AFM) observation. Multilayers were fabricated depositing monolayers onto glass substrates. The absorbance 492 nm due to cation in multilayer increased linearly increase layer number, indicating layer-by-layer deposition monolayers. Because no second-harmonic generation (SHG) signal from against number observed, orientation would be ...
