摘　　要：聚丙烯胺盐酸盐(PAH)与2-[{[2-(2-吡啶基)肼基]硫代羰基}氨基]乙酸(化合物2)经酰胺反应制得聚丙烯胺衍生物(PAH-S)。由聚乙烯亚胺(PEI)、PAH-S与聚苯乙烯苯磺酸钠(PSS)通过层层自组装制备聚电解质多层膜(PEMs)。采用质量敏感的石英晶体微天平技术实时监控聚电解质(PE)的静电层层自组装吸附过程。在PAH与化合物2摩尔配合比为10∶2,PO34-离子浓度达到10-2 mol条件下,频率降至150Hz,表明制得的PEMs对PO34-具有吸附响应性。PAH-S was synthesized by covalently attaching 2-({(E)-Hydrazino[2-(2-pyridyl)hydrazino]methyl}amino)acetic acid(compound 2)to poly(allylamine hydrochloride)(PAH)via carbodiimide-assisted coupling reaction in water at room temperature.The resulting PAH-S was used to prepare polyelectrolyte multilayers(PEMs)in combination with polyethylene imine(PEI)and poly(sodium 4-styrene sulfonate)(PSS)via layer-by-layer deposition.The polyelectrolyte(PE)adsorption processes were monitored in real time by quartz crystal microbalance(QCM).When the molar ratio of PAH to compound 2 wes 10∶2 and the concentration of PO34-ion reached 10-2 mol,the frequency decreased(150 Hz),indicating that the prepared PEMs was adsorption responsive to PO34-.
