Abstract

The new synthesized thiomacrocyclic ionophore 4-phenyl-4-sulfide-11-(1-oxodecyl)-1,7-dithia-11-aza-4-phosphacyclotetradecane has proven to form Langmuir and Langmuir-Blodgett (LB) films. This ionophore shows a large affinity for copper(II) ions. Thus, the influence of the subphase composition on the surface pressure-area isotherms has been studied. The LB films have been observed by AFM and the effect of the subphase composition and the deposition surface pressure on the LB films is discussed. AFM image morphology has been correlated to the ionophore molecular structure. Surface pressure-area isotherms and AFM images show that the presence of copper(II) ions has an important role in the film structure.

摘要

新合成的硫代大环离子载体4-苯基-4-硫醚-11-(1-氧代癸基)-1,7-二硫杂-11-氮杂-4-磷杂环十四烷已被证明能形成朗缪尔（Langmuir）膜和朗缪尔-布洛杰特（LB）膜。这种离子载体对铜（II）离子表现出很大的亲和力。因此，研究了亚相组成对表面压力-面积等温线的影响。通过原子力显微镜（AFM）观察了LB膜，并讨论了亚相组成和沉积表面压力对LB膜的影响。AFM图像形态已与离子载体分子结构相关联。表面压力-面积等温线和AFM图像表明，铜（II）离子的存在对膜结构起着重要作用。
