Аннотация: The acidity and basicity constants of isomeric phenyl(aryl)-1,2,4-triazin- 3- and -5-ones in aqueous solution were determined by spectrophotometry: pK a = 7.3-6.2; pKBH+ = 0.1 to -2.2. 1,2,4-Triazin-3-ones are weaker bases than the corresponding 1,2,4-triazin-5-ones. According to the AM1 calculations, the most thermodynamically favorable tautomer in the gas phase is the oxo form: namely, 2H-tautomers of the neutral bases and 2,4-H,H +-tautomers of the conjugate acids.

Аннотация: The reduction of fluorinated ?-diketones (DK) is known to give ?-diols [G. Swalens, M. Anteunis and D. Tavernier, Bull. Soc. Chim. Belg., 79 (1970) 441–450] and ?-hydroxyketones (HK) II [A.L. Henne and P.E. Hinkamp, J. Am. Chem. Soc., 76 (1954) 5147]. We have established that the lithium salts (Ia) as well as chelate compounds of DK with zinc (Ib) and aluminium (Ic) undergo selective reduction with LiAlh4 to HK III. Salts (Id) and chelate compounds (If) are not reduced under the same conditions

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.

    Novel push-pull thieno[2,3-b]indole-based dyes for efficient dye-sensitized solar cells (DSSCs) / R. A. Irgashev, A. A. Karmatsky, G. A. Kim, G. L. Rusinov, V. N. Charushin, A. A. Sadovnikov, V. K. Ivanov, S. A. Kozyukhin, V. V. Emets, V. A. Grinberg // Arkivoc. - 2017. - Vol. 4. - P34-50

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.
