•The sensor based on diaza-18-crown-6 ether with dual coumarins was synthesized.•The sensor exhibited high selectivity and anti-disturbance property for Fe3 +.•The response toward Fe3 + was performed via coordination and charge transfer.•The sensor had a low detection limit (0.31 μM) and fast response time (10 s).
A new fluorescent chemosensor based on diaza-18-crown-6 ether, which was appended with dual coumarins, exhibited high selectivity and anti-disturbance for Fe3 + among environmentally and biologically relevant metal cations. Fe3 + sensing was performed via the complexation of Fe3 + ions with the chemosensor. In addition, the detection limit of the fluorescence response of the sensor to Fe3 + was 0.31 μM with a rapid response of less than 10 s.
