An electrochemical investigation of the transport of the crown ether 4
'-nitrobenzo-15-crown-5 across a water/1,2-dichloroethane interface sh
owed that the crown ether did not cross the interface but the complex
formed by the crown ether with Na+ did transfer, the peak transfer cur
rent increased with increasing [Na+] until all the crown ether was com
plexed. The in situ interfacial second harmonic generation experiment
indicates that, in the absence of Na+, the crown ether is oriented and
ordered by the electric field at the interface. The sodium coronate s
hows a more complex behaviour at the interface.
