“…As seen from Fig S5, the uorescence quenching for PA and Fe 3+ was occurred only within just 30 seconds, and at their uorescence intensities were reached to equilibrium at same response time. Thus, a response time was decided on 30 seconds for the following experiments and the chemoprobe IPC depicted an excellent response time towards PA and Fe 3+ respecting the formerly developed a lot of uorogenic dual chemoprobes [10,[19][20][21].…”

“…To keep away from these drawbacks, uorescent sensing systems have been recently developed due to their superior advantages mentioned above [7,[16][17][18]. However, the literatures based upon to fabricate dual responsive uorescent chemoprobes for the recognition of both PA and Fe 3+ with high selectivity and sensitivity, are still rare [10,[19][20][21]. Therefore, the need is great for more uorescent chemoprobes able to detect the PA and Fe 3+ in real-time and reliably.…”

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.

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.

“…There are numerous small molecule sensors as well to detect PA with low LOD. [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] Zinc oxide nanomaterials and fluorescent quantum dots were also helpful in PA detection. [57,58] The fluorescent outputs due to the sensing mechanisms were effectively used to prepare logic based devices in some cases.…”

Picric acid (PA) at low concentration is a serious water pollutant. Alongside, aliphatic amines (AAs) add to the queue to pollute surface water. Plenty of reports are available to sense PA with an ultralow limit of detection (LOD). However, only a handful of works are testified to detect AAs. A new fluorescent donor-acceptor compound has been synthesized with inherent intramolecular charge transfer (ICT) character that enables selective and sensitive colorimetric quantitative detection of PA and AAs with low LODs in nonaqueous as well as aqueous solutions. The synthesized compound is based on a hemicyanine skeleton containing two pyridenylmethylamino groups at the donor and a benzothiazole moiety at the acceptor ends. The detailed mechanisms and reaction dynamics are explained spectroscopically along with computational support. The fluorescence property of the detecting compound changes due to protonation of its pyridinyl centers by PA leading to quenching of fluorescence and subsequently de-protonation by AAs to revive the signal. We have further designed logic circuits from the acquired optical responses by sequential interactions.
