该报告表明，冠醚可以用硫醇官能团修饰并锚定到银表面而不损失活性。一旦连接的冠的响应度可以用表面增强拉曼光谱检查。所检测的冠醚是二氨基二苯并-18-冠醚-6-与巯基烟酸用DCC偶联形成酰胺。我们发现，衍生化的二氨基二苯并-18-冠-6响应碱金属氯化物。K的形成和选择性进行了测定，并遵循类似于在水溶液中观察到的趋势
This report demonstrates that crown ethers can be modified with thiol functionalities 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. The K formation and selectivity were determined and followed a trend similar to that observed in aqueous solutions
