• 关键词: XAFS; air-solution interface; total-reflection X-ray absorption spectroscopy (total-reflection XAS); monolayer; orientation of metal complex

The purpose of this project is to develop a new spectroscopic method to study the solvation structures of ions which lie on the air-solution interface. The present method is an XAFS technique operated under the total-reflection condition at the solution surface. Due to a very small acceptance angle onto the solution surface for the total-reflection condition at X-ray region, the experiment can be performed only by using synchrotron radiation. We could successfully study the surface concentration of Br ions and its solvation structures which were segregated to the solution surface by alkylammonium. Another study was a polarization dependent XAFS applied to planar Zn- and Cu-complexes formed at the solution surface. From the polarization XAFS the preferential orientation of the complexes could be determined.

该项目的目的是开发一种新的光谱方法来研究空气-溶液界面上离子的溶剂化结构。本方法是在溶液表面全反射条件下操作的XAFS技术。由于X射线区域全反射条件下溶液表面的接受角非常小，因此只能使用同步加速器辐射进行实验。我们可以成功地研究溴离子的表面浓度及其被烷基铵偏析到溶液表面的溶剂化结构。另一项研究是将偏振相关的 XAFS 应用于溶液表面形成的平面锌和铜复合物。从偏振 XAFS 可以确定复合物的优先取向。
