Аннотация: Extensive research on the synthesis and application of tetrazine derivatives for electronic devices, luminescent elements, photoelectric conversion elements, and image sensors has been published recently. This review covers reported data on the modern trends in the design of functionalized tetrazines obtained within the period 2010–2020. Aryl(heteroaryl) and arylvinyl derivatives of tetrazines and their photoluminescence and application for fluorogenic probes are discussed. Examples of photosensitive oligomers and polymer 3,6-dithienyltetrazines are reviewed.

Заглавие : Bispyrenylalkane chemosensor for the naked-eye detection of nitro-explosives

Ключевые слова (''Своб.индексиров.''): detection of explosives in aqueous media--chemical sensors--fluorescence quenching--pyrene-based fluorophores
Аннотация: Pyrene-based compounds have a great potential as fluorescent chemosensors for various analytes including common nitroexplosives, such as 2,4,6-trinitrotoluene (TNT). Compounds having two pyrene units in one molecule, such as bispyrenylalkanes, are able to form stable, bright emissive in a visual wavelength region excimers both in non-polar and polar environments. In this work we wish to report that in non-polar solvents the excimer has poor chemosensing properties while in aqueous solutions it provides significant “turn-off” fluorescence response to TNT in the subnanomolar concentrations.

Заглавие : Design of fluorescent sensors based on azaheterocyclic push-pull systems towards nitroaromatic explosives and related compounds: a review

Ключевые слова (''Своб.индексиров.''): nitroaromatic explosives--fluorescence quenching--pyridines--pyrazine--pyrimidines--triazines
Аннотация: Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azaheterocyclic scaffold, their functionality and their ability to detect of nitroaromatics by fluorescence quenching.

Заглавие : Synthesis and photophysical studies of novel v-shaped 2,3-bis{5-aryl-2-thienyl}(dibenzo[f,h])quinoxalines

Ключевые слова (''Своб.индексиров.''): cross-coupling--dibenzo[f,h]quinoxaline--donor-acceptor-donor chromophores--fluorescence--sensors
Аннотация: A series of novel V-shaped luminophores containing electron-withdrawing dibenzo[f,h]quinoxaline core and arylthienyl donor fragments at positions 2 and 3 has been synthesized. The absorption spectra (UV/vis) were recorded in several solvents, whereas emission spectra were recorded in solutions and powders. The solvatochromism as well as halochromism of obtained compounds was also explored. Electronic-structure calculations using quantum-chemistry methods were performed to further analyse experimental results. All characteristics were compared with that of 2,3-bis(arylthienyl)quinoxaline counterparts. The halochromic effect studies showed that upon gradual addition of trifluoroacetic acid (TFA) to the toluene solution of diethylaminophenyl-substituted dibenzo[f,h]quinoxaline chromophore, absorption and emission changed. Observed band shifts were more distinct in the case of mentioned quinoxaline than for other derivatives. All of the (dibenzo[f,h])quinoxaline chromophores exhibited good sensitivity toward nitro-containing explosives with high Stern-Volmer constants up to 57800 M−1, these results are remarkable for such heterocyclic systems.

Аннотация: In this paper, the new sensors based on the C(4) or/and C(5) mono(heteroaryl) and di(heteroaryl) substituted pyrimidines are described. The effect of different substituents in pyrimidine ring on the detection limits and selectivity for prepared sensors are explained. The results of detection towards various nitro-explosives and volatile interferents at room temperature with use of the portable detector “Nitroscan” are shown.

Ключевые слова (''Своб.индексиров.''): photophysics --charge transfe--fluorescence
Аннотация: The synthesis of a series of push-pull aryl and arylethynyl 2-(thiophen-2-yl) quinazoline derivatives is presented. The photophysical properties of the newly generated compounds are also described. Functionalization of the (2-thienyl) quinazoline fluorophore at the 5'-position with aryl and arylethynyl moieties was performed using bromination and subsequent palladium-catalyzed cross-coupling reactions. Optical studies revealed that 4-(diethylamino) phenyl and 4-(diphen-ylamino) phenyl derivatives emit green light upon irradiation, whereas their 4-(9H-carbazol-9-yl) phenyl, methoxyphenyl, thienyl and arylethynyl counterparts are characterized by blue light emission capabilities. The effect of protonation has also been studied, and the ability of some of these molecules to function as colorimetric and luminescent pH sensors has been demonstrated with significant color changes and luminescence switching upon the introduction of acid.

Заглавие : Iptycene-Based Fluorescent Sensors for Nitroaromatics and TNT

Ключевые слова (''Своб.индексиров.''): explosives--fluorescence spectroscopy--nanofibres--sensors
Аннотация: Small-molecule fluorescent sensors (1–5) for the recognition of nitroaromatic compounds, such as 2,4-dinitrotoluene and the explosive TNT, were obtained by using a three-step dehydrohalogenation cycloaddition protocol. The interaction of the receptors and nitroaromatics was studied both in solution and in the solid state by using fluorescence spectroscopy and X-ray crystallography, respectively. It is shown that the iptycene receptors 1–5 provide a cavity suitable for binding nitroaromatic compounds in an edge-to-face mode, rather than simple ring-stacking interactions. The results obtained inspired us to develop an inexpensive, reliable and robust sensor for vapour detection of explosives. Polymer nanofibres are particularly suitable for the production of such TNT sensors as they accelerate the mass exchange between the polymer and the vapours of TNT. Quenching of the sensors took place within 1 min compared to 10 min for a glass-slide assay. Hence, the sensor performance can be improved by optimising the matrix material and morphology without resynthesising the sensor moieties
