摘要
A bolaform amphiphile(BP-15) bearing biphenyl group and long spacers of alkyl chains was synthesized. In-situ AFM studies indicate that the amphiphile can form two kinds of surface aggregates with different morphologies depending on solution concentration: short-range ordered cylindrical surface micelles at the lower concentration and flat domains at the higher concentration. These results agree well with the two critical micelle concentrations in bulk solution as determined by the concentration-dependent conductivity.
