SERS Study of the Interaction of Alkali Metal Ions with a Thiol-DerivatizedDibenzo-18-Crown-6

摘要

This report demonstrates that crown ethers can be modified with thiolfunctionalities and anchored to silver surfaces without loss of activity. Once attached the responsivity of the crown can be examined with surface-enhanced Raman spectroscopy. The crown examined was a diaminodibenzo-18-crown-6 coupled to mercaptonicotinic acid with DCC to form an amide. We found that the derivitized diaminodibenzo-18-crown-6 responded to alkali chlorides.
