Interfacial Assembly of Two Gemini-type Schiff Base Amphiphiles with Aromatic Spacers in Organized Molecular Films

摘要：

　　Gemini amphiphiles have been widely investigated in many aspects due to the unique structure.In this study,two gemini-type Schiff base amphiphiles containing aromatic spacers were synthesized and characterized in Langmuir-Blodgett films.Both compounds formed stable multilayer films and showed distinct phase behaviours on water surface and ion subphase.When the compounds spread on Cu(II) ions subphase,an in-situ coordination occurred for both ligands.While spectral measurements confirmed the coordination with Cu(II) ions and aggregation mode,the morphological investigations showed the distinct nanostructures and molecular rearrangement depended on the molecular spacers and aggregation modes.For both process,the aromatic spacers in gemini amphiphiles have predominant effect in regulating the aggregation modes and spectral changes in organized molecular films.
