摘要

We describe the synthesis and characterization of the mesogen-bearing bolaform amphiphile 4,4'-dihydroxybi-phenylbis(11-pyridinium-N-yl-undeca-noic ester) dibromide (BP-10) and its solid/liquid interfacial self-assembly, Cylindrical micelles are directly observed by atomic force microscopy (AFM) at the interface between mica and the aqueous solution above the critical micelle concentration (cmc). In situ and exsitu AFM studies indicate that the cylindrical micelles are stable both at the mica/solution interface and in the dry state. The enhanced stability of the micellar structures enables a detailed investigation of their self-assembly behavior and supramolecular structures at the interface. THe adsorption model proposed here is supported by the variation of the interfacial self-assemblies on changing the solution concentration and substrate temperature.
