transitions. Benefiting from its chemical stability and luminescent properties, compound 2 possesses multi-functional fluorescent responses toward the Fe3+ ion, the Cr2O72- ion and the NZF antibiotic in aqueous medium. The KSV values of compound 2 are 4.68 × 104 M-1 for the Fe3+ ion, 7.23 × 104 M-1 for the Cr2O72- anion, and 1.03 × 104 M-1 for the NZF antibiotic. Additionally, the possible mechanism for the
