Ключевые слова (''Своб.индексиров.''): organic dyes --pyrimidine--microwave-assisted
Аннотация: Six novel donor–π–acceptor organic dyes bearing a pyrimidine as the anchoring group have been obtained in good yields by combination of the microwave-assisted Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen reactions. Their absorption, photoluminescence and electrochemical properties were fully investigated in detail. The infrared spectra of dyes adsorbed on TiO2 indicate the formation of coordinate bonds between the pyrimidine ring of dyes and the Lewis acid sites (exposed Tin+ cations) of the TiO2 surface. This work demonstrates that the pyrimidine rings of dye sensitizers that form a coordinate bond with the Lewis acid site of a TiO2 surface are promising candidates as the electron-withdrawing anchoring group. The data from quantum calculations show that all of the dyes are potentially good photosensitizers for dye-sensitized solar cells

Ключевые слова (''Своб.индексиров.''): thieno[2,3-b]indole --dyes--thiophene
Аннотация: Two novel dyes IK-1,2 bearing the 8-alkyl-8H-thieno[2,3-b]indole unit as an electron-donating part of the push-pull system have been designed and prepared, as promising sensitizers for solar cells. The key steps of the synthesis involve the crotonic condensation of 1-alkylisatins with 2-acetylthiophene, followed by reduction of the C=C double bond and further cyclization through the Paal-Knorr reaction with the Lawesson reagent, thus leading to the formation of 2-(thien-2-yl) substituted thieno[2,3-b] indole derivatives. The optical and electrochemical properties of these dye's have been investigated by using spectrophotometry and cyclic voltammetry respectively, while their photovoltaic performance was evaluated by a device fabricatien study. The DSSCs based on IK-1 and IK-2 have demonstrated an efficiency of eta = 0.37% (FF = 73%) and eta = 0.7g% (FF = 69%) under 100 mW cm(-2) simulated AM 1.5G solar irradiation, respectively.

Ключевые слова (''Своб.индексиров.''): pyrimidines--carbazole--dye-sensitized solar cells
Аннотация: Novel donor-pi-acceptor dyes bearing the pyrimidine unit as an electron-withdrawing group have been synthesized by using combination of two processes, based on the microwave-assisted Suzuki cross-coupling reaction and nucleophilic aromatic substitution of hydrogen. Spectral properties of the obtained dyes in six aprotic solvents of various polarities have been studied by ultraviolet-visible and fluorescence spectroscopy. In contrast to the absorption spectra, fluorescence emission spectra displayed a strong dependence from their solvent polarities. The nature of the observed long wavelength maxima has been elucidated by means of quantum chemical calculations. The electrochemical properties of these dyes have been investigated by using cyclic voltammetry, while their photovoltaic performance was evaluated by a device fabrication study. The experimental and calculation data show that all of the dyes can be regarded as potentially good photosensitizers for dye-sensitized solar cells.

Ключевые слова (''Своб.индексиров.''): 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.

Ключевые слова (''Своб.индексиров.''): carbazole --nitroaromatic explosives--triphenylamine
Аннотация: A number of D-pi-A type dyes on the basis of new 2H[1,2,3]triazolo[4,5-e][1,2,4]triazolo[1,5-a]pyrimidines, bearing various electron-donating carbazole and triphenylamine fragments, have been studied as sensing fluorophores. Fluorescence studies have demonstrated that emission spectra of these compounds in acetonitrile are sensitive to the presence of nitroaromatic explosives, such as 2,4-dinitroanisole (DNAN), picric acid (PA), styphnic acid (SA), 1,3,5-triethoxy-2,4,6-trinitrobenzene (TETNB), 2,4-dinitrotoluene (DNT), 2,4,6-trinitrotoluene (TNT) and nitrobenzene (NB). Detection limits of fluorophores for DNAN, PA, SA, TETNB, DNT and TNT proved to be in the range from 4.82x10(-1) to 2.96x10(-3) mol/L, 2.10x10(-3) to 5.98x10(-5) mol/L, 1.26x10(-1) to 2.02x10(-4) mol/L, 1.58 x 10(-1) to 1.62x10(-3) mol/L, 1.26x10(-1) to 5.61x10(-4) mol/L and 9.01x10(-2) to 2.77x10(-3) mol/L, respectively. Selective fluorescence quenching response, including a sharp color change under UV irradiation (especially for PA, SA and DNT), makes these compounds promising fluorescence chemosensors for nitroaromatic explosives

Ключевые слова (''Своб.индексиров.''): dye-sensitized solar cells--electron-rich heterocycles--metal-free dyes--photovoltaic properties--push-pull structure--thieno[2,3-b]indole
Аннотация: New metal-free sensitizers (IK 3-6), based on the thieno[2,3-b]indole ring system, bearing various aliphatic substituents at the nitrogen atom (electron-donating part), several thiophene units (π-bridge linker) and 2-cyanoacrylic acid (the electron-accepting and anchoring group) have been synthesized for application in dye-sensitized solar cells (DSSCs). The relationship between the IK dye structure and efficiency of the corresponding DSSC has been elucidated. Power conversion efficiency (PCE) up to 6.3% (short-circuit photocurrent density (JSC) 19.0 mA cm-2, open-circuit voltage (VOC) 0.59 V, and fill factor (FF) 56.4%) were obtained for the DSSC, based on 2-cyano-3-{5-[8-(2-ethylhexyl)-8H-thieno[2,3-b]indol-2-yl]thiophen-2-yl}acrylic acid (IK 3), which proved to be a highly synthetic available compound, under simulated AM 1.5 G irradiation (100 mW cm-2), thus indicating that thieno[2,3-b]indole-based organic dyes are perspective candidates for DSSCs.
