摘要

目的：为研制有机纳米材料的光电器件.方法：设计合成了一种新的含长链烷基的8-氨基喹啉衍生物，2－十二烷基丙二酸二（8－氨基喹啉）酰胺（H2A）两亲配体，研究了亚相不同金属离子对其成膜性能的影响，特别是不同浓度的亚相Cu2+和不同铜盐对H2A成膜性能的影响.结果：Cu2+离子对H2A具有特殊的配位作用.结论：新型配体与铜离子的特殊配位作用，可使其单分子膜或多层膜在化学传感器方面存在潜在的应用前景.%Aim: To develop photoelectricity devices of nanometer organicmaterial. Methods: A new long alkyl chain 8－aminoquinoline amphiphilic ligand (H2A) was synthesized and characterized by elemental analyses, IR and 1H NMR. The behaviors of the monolayer of H2A on subphases containing different metal ions, various concentrations of copper ion and different counterions were investigated. Results: Copper ion has special coordination to the amphiphilic ligand. Concentrations of copper ion have remarkable effect on the coordination. Conclusion: This special coordination behavior of H2A monolayer to Cu2+ ion makes it possible to fabricate Cu2+ ion sensor.
