Selective two way Cd(II) and Co(II) ions detection by 1,2,3–triazole linked fluorescein derivative

[Display omitted] •The paper insights about the sensing of Cd(II) and Co(II) ions by a fluorescein derivative.•The senor efficiently recognizes Cd(II) and Co(II) ions competitively in a mixture of cations.•The Cd(II) ion detection is a solvent induced phenomenon and displays self-quenching in chloro...
