Anion Transfer At A Micro-water/1,2-dichloroethane Interface Facilitated By β-octafluoro-meso-octamethylcalix[4]pyrrole

摘要

Due to its potential importance in drug delivery and value in understanding ion transport across biomembranes, facilitated ion transfer (FIT) at liquid/liquid (L/L) interfaces has been widely investigated since the pioneering work of Koryta in 1979. To date, most reports in this area have focused on facilitated cation transfer (FCT). In spite of great advances in the area of anion recognition chemistry, few studies involving facilitated anion transfer (FAT) at L/L interfaces have been published, and even fewer reports regarding a kinetic analysis of the underlying phenomenon have appeared. Given this lack of available dynamic information, we have used electrochemical methods to study the thermodynamic and kinetic transfer behavior of several monovalent anions at a micropipet-supported micro-water/1,2-dichloroefhane (μ-W/DCE) interface.
