    5-Aryl-2,2-bipyridines as tunable fluorophores [Text] / D. N. Kozhevnikov, O. V. Shabunina, D. S. Kopchuk, P. A. Slepukhin, V. N. Kozhevnikov // Tetrahedron Letters. - 2006. - Vol. 47, № 39. - P7025-7029

Аннотация: Readily available 5-aryl-2,2?-bipyridines and their derivatives are a unique family of fine-tunable chromophores, where changes in the substitution patterns, solvation and coordination are translated into dramatic spectral changes. They exhibit sensitive and selective response to zinc ions with dramatic increases in emission intensity or significant red-shifts of emission maxima????

Аннотация: This review is focused on consideration of effects of the nature of N,​N'- and N,​O-​bidentate ligands on the structure and optical properties of their B(III) complexes. It has been established that B(III) complexes with asym. N,​N'- and N,​O-​bidentate ligands, such as ortho-​hydroxyphenyl substituted azaheterocycles and heteryl-​β-​ketoimines, exhibit large Stokes shifts, enhanced intensity, and extended range for luminescence in solns. as well as in solid state, comparable with characteristics of the family of BODIPYs derivs. Complexes of some bidentate ligands can be considered as promising fluorophores for applications in biomedical imaging, electroluminescent, solar cell devices, and other fields.

NITROAROMATIC EXPLOSIVES -- PYRIMIDINE SCAFFOLD
Аннотация: A series of D-​π-​A- type dyes based on pyrimidines, bearing various thiophene linkers, have been studied as sensing fluorophores. Fluorescence studies have demonstrated that the emission of all derivs. is sensitive to the presence of nitroarom. explosives, such as 2,​4,​6-​trinitrophenol (PA)​, 2,​4,​6-​trinitrotoluene (TNT)​, and 2,​4-​dinitrotoluene (DNT)​, in their acetonitrile solns. The detection limits of fluorophores to PA, TNT, and DNT proved to be in the range from 5.83 × 10-​6 to 2.38 × 10-​7 mol​/L, 1.70 × 10-​4 to 8.40 × 10-​6 mol​/L, and 8.39 × 10-​5 to 6.87 × 10-​6 mol​/L, resp. The theor. investigation into the quenching mechanism in the presence of fluorophore has been performed. All compds. have shown a good efficiency as sensor materials when tested as elements of the original device <> for detecting nitro-​contg. explosives in vapor phase

4,5-DI(HETERO)ARYLPYRIMIDINES -- NITROAROMATIC EXPLOSIVES -- VAPOR PHASE
Аннотация: A series of D–π–A–π–D type dyes based on pyrimidines, bearing thiophene linkers, have been studied as sensing fluorophores. Fluorescence studies have demonstrated that the emission of all derivatives is sensitive to the presence of 2,4,6-trinitrotoluene (TNT) and other nitroaromatic compounds (NACs), in their acetonitrile solutions. The detection limits of fluorophores to NACs proved to be in the range from 10−4 to 10−6 mol/L. The time-resolved fluorescence measurements and theoretical investigation into the quenching mechanism in the presence of fluorophore has been performed. The two types of sensor prototypes for handheld sniffer «Nitroscan» (Plant «Promautomatika», Ekaterinburg, Russia) on the basis of non-woven dry wipe and spunlace non-woven fabric with various quantities of the most sensitive fluorophore have been fabricated. The reusable, reversible and sensitive response of the designed prototypes to NACs enables one to qualify these compounds as promising fluorescent sensory materials for detection of NACs.

ALIPHATIC AMINES -- FLUORESCENCE QUENCHING -- NITROAROMATIC COMPOUNDS -- PYRAZINE -- QUINOXALINE -- SOLVATOCHROMISM
Аннотация: Novel 1,4-diazine-based dyes of the D–π–A type, possessing triphenylamine as an electron-donating group, have been developed. Fluorescence studies have demonstrated that emission of these fluorophores is sensitive towards different nitroaromatic compounds and aliphatic amines, both in solutions and in a vapor phase. Moreover, these compounds can be considered as “naked-eye” fluorescent probes for solution polarity because they possess pronounced solvatochromic properties. Therefore, these compounds have to be regarded as potential multifunctional chemosensors for monitoring hazardous organic substances.

Аннотация: A number of novel fluorinated derivatives of the family of pyrido[1,2-a]indole fluorophores have first been synthesized via the aryne-mediated domino transformations of 5-(perfluorophenyl)-3-(pyridin-2-yl)-1,2,4-triazines. A comprehensive study of photophysical properties of the obtained polyfluoroaryl substituted derivatives, in which polyfluoroaryl, 1,2,3-triazole, and pyridoindole subunits contribute to a joint chromophore system, has shown that these compounds proved to exhibit a fluoresce with green light in acetonitrile solutions.
