“…However, the adsorption of CEES and hexane into Zr-BDC (UiO-66) and other Zr-based MOFs have also been shown in literature. [47][48][49] This helps to explain the comparable signals observed between CEES, DMMP and hexane.…”

“…Previously, we reported the use of fluorescein encapsulated Zr‐BTC for the detection of 2‐chloroethyl ethyl sulfide (CEES), also known as half mustard gas. [ 49 ] The alteration of the fluorescent material and the organic ligand substantially reduces the fluorescence quenching from CEES and instead yields substantial fluorescence quenching in the presence of DMMP. The material is also not affected by common VOCs such as hexane.…”

Chemical warfare agents are toxic chemicals that require rapid, easy‐to‐use, sensitive, and selective sensors to countermeasure. Simulants, such as dimethyl methyl phosphonate (DMMP), are used to test the effectiveness of sensors toward nerve agents. Metal organic frameworks (MOFs) offer large surface area and selective accessibility to active sites making them appealing for chemical sensing applications. In this work, we propose a fast, facile, direct synthesis method for manufacturing fluorescent MOFs with high sensitivity and selectivity. Zr‐BDC is synthesized with 1, 4‐benzenedicarboxylic acid (BDC) as an organic ligand and zirconium (Zr) metal. Fluorescent materials are then encapsulated in a novel and rapid in situ approach with strong solvents. X‐ray diffraction, UV–visible spectroscopy, Fourier‐transform infrared spectroscopy, and Raman spectroscopy are used to verify the successful formation of fluorescent MOFs. Compared to other methods, the gel synthesis method helps to control crystal growth leading to higher BET surface areas of ~1150 m2 g−1 for Zr‐BDC and 850 m2 g−1 for ZrQ@Zr‐BDC. Titration experiments show the sensitivity of the material to DMMP down to 8.3 nM with a highly linear response. Enhanced fluorescence and occupation of mesopores by ZrQ enable lower limit of detection than those of comparable works in literature. The encapsulation mechanism also prevents substantial defects that would otherwise lead to water adsorption.

Detection of chemical warfare agents and toxic industrial chemicals is very important for security forces. For a long time it has been based on colorimetric chemistry, and only the development of electronics has made the automation and miniaturisation of chemical detection possible. At the end of the 20 th century, automatic chemical detectors, mostly based on ion mobility spectrometry technology (IMS), began to appear on the market. Nowadays, colorimetric detectors are increasingly being used again due to their excellent selectivity and low cost, and new chromogenic reagents are being developed. On the other hand, the development of IMS detectors is focused on the use of an asymmetric field since it allows smaller dimensions and greater sensitivity of the detector. In this paper, besides commercially available chemical detectors based on colorimetry and ion mobility spectroscopy techniques, an overview of scientific research focused on further development of these technologies with the goal of increasing selectivity and sensitivity is given.

“…26 Furthermore, Abuzalat and co-workers successfully synthesized a functionalized MOF material Zr-BTC for the selective detection of 2-CEES at trace levels with an LOD of 48 ppb. 27 Obviously, great efforts have been made in the development of fluorescent chemosensors for 2-CEES detection. Nevertheless, there are still many remaining issues needed to be overcome for the 2-CEES fluorescent chemosensors, including the long synthetic processes of the sensing materials, the complex detection strategy, additional steps, and harsh test conditions.…”

Ultrafast Sulfur Mustard Simulant Gas Fluorescent Chemosensors Based on Triazole AIEE Material with High Selectivity and Sensitivity at Room Temperature

Herein, a novel blue aggregation-induced enhanced emission (AIEE) material 4-N-(naphthalen-l-yl)-3,5-bis(4-N-phenyl-1-naphthylamine)phenyl-4H-1,2,4-triazole (NDTAZ) is developed and used as a fluorescent chemosensor for sulfur mustard (SM) simulant 2-chloroethyl ethyl sulfide (2-CEES) vapor. The NDTAZ chemosensor is designed by introducing an electron-donating N-phenyl-1-naphthylamine group at 3 and 5 position of 4H-1,2,4-triazole (TAZ) to enhance the nucleophilicity of the TAZ group, and a naphthalene ring is connected to 4 position of the TAZ group to construct an AIEE molecule. The NDTAZ films show extraordinary stability and then are further used as reliable and portable fluorescent chemosensors. Upon exposure to 2-CEES vapor, the NDTAZ chemosensor exhibits an instantaneous fluorescence response (not more than 1 s). What should be noted is that this fluorescent chemosensor realizes the visualized detection of fluorescent color change from blue to green at “room temperature”, which is rarely reported. The limit of detection is estimated to be 0.55 ppm, which is below the AEGL-1 (0.6 ppm for 1 min) safety ceiling level to SM exposure. Moreover, the NDTAZ chemosensor shows high selectivity toward 2-CEES vapor over closely related substances, including alkylating agents, aryl halide compounds, sulphur-containing compounds, and nerve agent mimics. More impressively, the NDTAZ chemosensor demonstrates good recyclability by water treatment. Also, the sensing mechanism is adequately proved by using multiple experimental methods and theoretical calculation. In addition, the NDTAZ-based facile filter paper-constructed test strips are fabricated for real-time and on-spot detection of leaked 2-CEES gas specifically. Therefore, this fluorescent chemosensor with excellent sensing performance greatly advances the practical detection of SM species at room temperature.
