Two kinds of fluorescent sensors (S and S-1) for Fe3+ bearing H-1-Imidazo [4,5-b] phenazine derivatives have been designed and synthesized. Between the two sensors, S showed excellent fluorescent specific selectivity and high sensitivity for Fe3+ in DMSO solution. The test strip based on S was fabricated, which could act as a convenient and efficient Fe3+ test kit. The recognition mechanism of the sensor toward Fe3+ was evaluated by MS, IR and XRD. The detection limit of the sensor S towards Fe3+ is 4.8 x 10(-6) M. And other cations, including Hg2+, Ag+, Ca2+, Cu2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cr3+, and Mg2+ had no influence on the probing behavior.
