The probe FFIZNA could selectively monitor Al3+ and Zn2+ among other relevant cations with diverse colors through a turn-on emission response in EtOH:HEPES (9/1;v/v) media owing to the chelation enhanced fluorescence (CHEF), prevention of ESIPT, -C=N- isomerization and PET of the probe FFIZNA. The interactions of Al3+ and Zn2+ with the probe FFIZNA were confirmed by emission spectroscopy, Job's plot and H-1-NMR titration substantiated 1:2 reaction stoichiometry between FFIZNA and Al3+ and Zn2+. The time-response study displayed that the emission of FFIZNA with Al3+ and Zn2+, rapidly boosted and reached the stable value in less than 3.0 and 4.0 min, respectively. Therefore, the FFIZNA has successfully been utilized to the dual recognition of Al3+ and Zn2+ in solutions.eninfo:eu-repo/semantics/closedAccessIsoniazidFluorogenic sensorAluminumZincESIPTArticle31379780510.1007/s10895-021-02704-5337130102-s2.0-85102339748Q1WOS:000628074800001Q3
