“…These titration data were also employed to compute the association constants (log K) of IPC-PA and IPC-Fe 3+ complexes, and they were found to be 6.72×10 2 M −1 for PA and 3.62 M −1/3 for Fe 3+ on the basis of Benesi-Hildebrand equation (Fig. 3) [26][27][28]. Thus, these ndings recommended that the chemoprobe IPC has a great potential of recognition quantitatively unidenti ed concentrations of PA or…”

A propylimidazole functionalized coumarin derivative (IPC) was fabricated for the first time and applied as a dual responsive fluorescent chemoprobe for sensitive and selective recognitions of picric acid (PA) and Fe3+. Strong fluorescence quenching phenomena of the IPC were observed in H2O/ACN (5/95, v/v) medium (λem=408 nm) upon the additions of Fe3+or PA. The fabricated dual responsive IPC offered good selectivity and sensitivity with the low limit of detection values (0.92 µM for PA and 0.22 µM for Fe3+) lower than the acceptable amounts of Fe3+ and PA by the international official authorities. The interaction phenomena of IPC with PA and Fe3+ based on the findings of a range of experiments were considered and DFT computations were done to verify their recognition mechanisms. The sensing phenomena of IPC towards PA (1:1) and Fe3+ (3:1) were confirmed by the MALDI TOF–MS, FT–IR, 1H–NMR titration and Job's methods. Furthermore, the compound IPC was effectively applied as a fluorescent sensor for Fe3+ and PA detection in real natural spring water samples.

A propylimidazole functionalized coumarin derivative (IPC) was fabricated for the rst time and applied as a dual responsive uorescent chemoprobe for sensitive and selective recognitions of picric acid (PA) and Fe 3+ . Strong uorescence quenching phenomena of the IPC were observed in H 2 O/ACN (5/95, v/v) medium (λ em =408 nm) upon the additions of Fe 3+ or PA. The fabricated dual responsive IPC offered good selectivity and sensitivity with the low limit of detection values (0.92 µM for PA and 0.22 µM for Fe 3+ ) lower than the acceptable amounts of Fe 3+ and PA by the international o cial authorities. The interaction phenomena of IPC with PA and Fe 3+ based on the ndings of a range of experiments were considered and DFT computations were done to verify their recognition mechanisms. The sensing phenomena of IPC towards PA (1:1) and Fe 3+ (3:1) were con rmed by the MALDI TOF-MS, FT-IR, 1 H-NMR titration and Job's methods. Furthermore, the compound IPC was effectively applied as a uorescent sensor for Fe 3+ and PA detection in real natural spring water samples.
