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 Fe3+ in non-buffered aqueous solution without interference with the background metal ions (Li+, Na+, K+, Mg2+, Ca2+, Al3+, Cr3+, Mn2+, Fe2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+ and Ga3+). Additionally, the immobilization of this new selective iron probe was successfully achieved on gold electrode by electro-polymerization and monitored by EQCM.
