A fluorescent probe based on ICT for selective detection of benzenethiol derivatives

This work presented a benzothiazole-based fluorescent probe for the detection of benzenethiol derivatives using 2, 4-dinitrobenzene moiety as a sensing unit. This probe (NCABT) was able to instantaneously respond to 4-methylbenzenethiol (MTP) within 5 min. In detecting MTP, this probe displayed a low limit of detection (49 nM). Furthermore, the probe has been proved to have the potential to detect benzenethiol derivatives with electron-donating group in real water samples.

A new turn-on fluorescent probe for sensing 4-methylbenzenethiol in real water samples

A new fluorescent probe (MBT) for the detection of 4-methylbenzenethiol (p-MePhSH) was developed by using 4-(benzo[d]thiazol-2-yl)-3-methoxyphenol as the fluorophore and 2,4-dinitrophenyl ether as the sensing moiety. Probe MBT displayed good selectivity toward p-MePhSH in DMSO/PBS buffer (5/5, v/v) solution and anti-interference over other competitive species via nucleophilic aromatic substitution. The fluorescence intensities of the probe responded p-MePhSH showed a 22-fold enhancement and good linearity with p-MePhSH concentration collected in the range of 0–15 μM. Moreover, the probe is sensitive to p-MePhSH and the limit of detection is 45 nM. The sensing mechanism of probe MBT was verified by high-resolution mass spectrometry and fluorescence lifetime. Furthermore, the probe was used to the detection of p-MePhSH in real water samples.

Bimolecular photoactvarion of NBD fluorescence

The concatenation of a photochemical transformation with a chemical reaction allows the activation of nitrobenzoxadiazole (NBD) fluorescence under optical control. Specifically, the coupling of photoinduced deprotection with nucleophilic substitution converts a nonemissive NBD chromophore into a fluorescent product. These operating principles can evolve into a general mechanism to implement fluorescent switches based on the attractive photophysical properties of NBDs.
