New polymethine cyanine dyes covering hepta methine cyanine dyes (tricarbocyanine dyes) and nonamethine cyanine dyes (tetracarbocyanine dyes) derived from the nucleus benzo[(2,3-b)benzoxazine; (2′,3′-b’)furo (3,2- d)pyrazole] were designed and prepared using novel synthetic strategy. Electronic transitions for all the synthesized cyanine dyes was determined and evaluated through investigating their electronic visible absorption spectra in 95% ethanol solution The dyes were thought to be better electronic transitions when they absorb light at higher wavelength bands (bathochromic shifted and/or red shifted dyes). Consequently, the electronic transitions of the dyes decreases when they absorb light at lower wavelength bands (hypsochromic shifted and/or blue shifted dyes). Solvatochromic and/or halochromic evaluation for some selected dyes was carried out and determined through examining their electronic visible absorption spectra in 6 (six) pure solvents having different polarities [water (78.54), DMF (36.70), ethanol (24.3), chloroform (4.806), carbontetrachloride (2.238) and dioxane (2.209)] and/or in 8 (eight) aqueous universal buffer solutions owing varied pH values (1.99, 2.99, 4.30, 6.87, 7.96, 8.91, 10.55 and 12.04 units), resp. Structural characterization and determination was carried out via elemental anal., visible, mass, IR and ¹HNMR spectroscopic data.

Cha, Soon Wook published the artcileSynthesis and luminescence properties of four-armed conjugated structures containing 1,3,4-oxadiazole moieties, Computed Properties of 39115-95-2, the publication is Journal of Materials Chemistry (2003), 13(8), 1900-1904, database is CAplus.

New 9,10-bis(phenylethynyl)anthracene-cored, four-armed conjugated structures in which the 1,3,4-oxadiazole ring was used to link the surface alkyl tail groups, were synthesized and the luminescence properties of thin films prepared therefrom were studied. The four-armed compound (ANTH-OXA6t-OC₁₂) with the dodecyloxy surface group is a high glass transition temperature (T_g: 211°) material and exhibits good solubility in common organic solvents and, surprisingly, results in good quality thin films by spin-coating from solutions In contrast, the compound with tert-Bu surface groups shows poor solubility and gives films of inferior quality. When the films were exposed to UV light of 335 nm, they emitted mainly strong red light (500-750 nm) with much weaker emission at 375-450 nm. The (phenylethynyl)anthracene core is the only red light emitting chromophore in the structure, and the diphenyloxadiazole moieties are the shorter wavelength light emitters. In contrast, an electroluminescence (EL) device having the configuration of ITO/PEDOT-PSS/ANTH-OXA6t-OC₁₂/Li:Al emits only red light with an external quantum efficiency of 0.02% indicating that the outer diphenyloxadiazole moieties act only as electron transporters.

Han, Jie published the artcileThermotropic liquid crystals based on extended 2,5-disubstituted-1,3,4-oxadiazoles: structure-property relationships, variable-temperature powder X-ray diffraction, and small-angle X-ray scattering studies, Safety of 4-Iodobenzohydrazide, the publication is Chemistry – An Asian Journal (2006), 1(6), 814-825, database is CAplus and MEDLINE.

A class of extended 2,5-disubstituted-1,3,4-oxadiazoles R¹-C₆H₄-{OC₂N₂}-C₆H₄-R² (R¹ = R² = C₁₀H₂₁O 1a, p-C₁₀H₂₁O-C₆H₄-CC 3a, p-CH₃O-C₆H₄-CC 3b; R¹ = C₁₀H₂₁O, R² = CH₃O 1b, (CH₃)₂N 1c; F 1d; R¹ = C₁₀H₂₁O-C₆H₄-CC, R² = C₁₀H₂₁O 2a, CH₃O 2b, (CH₃)₂N 2c, F 2d) were prepared, and their liquid-crystalline properties were examined In CH₂Cl₂ solution, these compounds displayed a room-temperature emission with λ_max at 340-471 nm and quantum yields of 0.73-0.97. Compounds 1d, 2a-2d, and 3a exhibited various thermotropic mesophases (monotropic, enantiotropic nematic/smectic), which were examined by polarized-light optical microscopy and differential scanning calorimetry. Structure determination by a direct-space approach using simulated annealing or parallel tempering of the powder x-ray diffraction data revealed distinctive crystal-packing arrangements for mesogenic mols. 2b and 3a, leading to different nematic mesophase behavior, with 2b being monotropic and 3a enantiotropic in the narrow temperature range of 200-210°. The structural transitions associated with these crystalline solids and their mesophases were studied by variable-temperature x-ray diffractometry. Nondestructive phase transitions (crystal-to-crystal, crystal-to-mesophase, mesophase-to-liquid) were observed in the diffractograms of 1b, 1d, 2b, 2d, and 3a measured at 25-200°. Powder x-ray diffraction and small-angle x-ray scattering data revealed that the structure of the annealed solid residue 2b reverted to its original crystal/mol. packing when the isotropic liquid was cooled to room temperature Structure-property relationships within these mesomorphic solids are discussed in the context of their mol. structures and intermol. interactions.

Nycz, Jacek E. published the artcileSynthesis, spectroscopy and computational studies of some novel π-conjugated vinyl N-alkylated quinolinium salts and their precursor’s, Application of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Journal of Molecular Structure (2016), 416-423, database is CAplus.

π-Conjugated vinyl N-methylated quinolinium salts (3) and their precursor’s N-alkylated quinolinium salts (2) were prepared and characterized by NMR, IR, UV-visible and MS spectroscopy. The hydroxyl and amino derivatives of vinyl N-methylated quinolinium salts lead to spiro type compounds (4). The syntheses of N-alkylated quinolinium salts were successful, and even multigram scale was achievable. The structures of 1,2-dimethylquinolinium iodide (2a) and 1-ethyl-2-methylquinolinium iodide (2b) were determined by single crystal x-ray diffraction method. NMR spectra showed readily diagnostic H-1 and C-13 signals from Me and N-alkyl groups for both 2 and 3. The geometries of the studied compounds were optimized in singlet states using the d. functional theory (DFT) method with B3LYP functional. In general, the predicted bond lengths and angles are in a good agreement with the values based on the x-ray crystal structure data.
