Abstract
Abstract A new N -azacrown carbazole fluoroionophore 1 was synthesized by microwave path and its sensing behavior toward metal ions was investigated by spectroscopic methods. This new structure proved to be an excellent selective fluorescent probe toward Fe 3+ in non-buffered aqueous solution without interference with the background metal ions (Li + , Na + , K + , Mg 2+ , Ca 2+ , Al 3+ , Cr 3+ , Mn 2+ , Fe 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Cd 2+ , Hg 2+ , Pb 2+ and Ga 3+ ). Additionally, the immobilization of this new selective iron probe was successfully achieved on gold electrode by electro-polymerization and monitored by EQCM.
