Rhodamine dye containing Isonicotinic hydrazide (RBN-1) is synthesized for the sensing of nitro aromatics, the probe showed turn-on fluorescence with Picric acid in co-existence with other interfering nitro aromatics. The sensor RBN-1 can be used for naked eye detection of picric acid with the detection limit of 37.3 nM in solution. The RBN-1 + PA complexation involves intermolecular hydrogen bonding between the pyridine N and the hydroxyl group of PA. The observed photophysical changes of RBN-1 with Picric acid is attributed to the spirolactam ring opening. The effective sensing ability of RBN-1 is tested in real water samples and paper strip experiments, the results are in good agreement with the pilot analysis.

Novel 2‐Arylbenzothiazoles: Selective Chromogenic and Fluorescent Probes for the Detection of Picric Acid

2018

A series of 2‐arylbenzothiazoles has been designed and synthesized as chromogenic and fluorescent probes for the detection of picric acid (PA) over other nitro analytes. A straightforward condensation of a variety of aryl nitriles with 2‐aminobenzenethiol under metal‐ and base‐free conditions afforded the corresponding products in 26–98% yields. All 2‐arylbenzothiazoles could efficiently sense PA at micromolar levels. The highly sensitive compound 2‐(4‐((2‐methyl‐1H‐imidazol‐1‐yl)methyl)phenyl)benzo[d]thiazole (3c) showed 95% fluorescence quenching on addition of 1.0 eq of PA which can be attributed to hydrogen bonding and ground state charge transfer complex formation with a detection limit of 19.0 μM. The high sensitivity of 3 c for PA detection was also established by test strips experiment. The sensing mechanism was explored by 1H NMR titrations and Job's plot.

“…In particular, tetraphenylethenes (TPE) with propeller-like structures have attracted much attention possibly due to the facile preparation and purication. The TPE and its derivatives have been intensively investigated and widely used as sensors for the detection of a variety of analysts [27][28][29] owing to high luminescence efficiency and good photostability.…”
