【Abstract】 Two novel amphiphilic poly(ester amine) dendrimers were synthesized and characterized by 1H NMR, 13 C NMR and IR spectra. Their properties of Langmuir film were investigated at the air/water interface. The relationship between the surface pressure and area isotherms of the dendrimers was found to be dependent on the nature of subphases. Interaction between HgCl 2 and the dendrimers was observed, indicating that the amphiphilic dendrimers could act as a sensor for Hg 2+ .
