Calix[4]arene derivative bearing pi-coordinate substituents as neutral carrier for silver ion sensors

摘要

Calix[4]arene tetra(allyl ether) 1 was applied as a neutral carrier of silver ion sensors, which exhibited an excellent silver ion selectivity against sodium ion, while calix[4]arene tetra(allyl ester) 2 possesses only poor silver ion selectivity with severe sodium ion interference. [References: 11]
