Résumé :
An Anaerobic/Aerobic SBR system was used to treat a synthetic wastewater with glucose and acetic acid (1000 mg/l COD) as carbon sources together with 20 and 100 mg/l of four different reactive dyes: disazo vinylsulphonyl, anthraquinone vinylsulphonyl, anthraquinone monochlorotriazinyle and oxazine. The decolorization efficiencies of the first three dyes at the 20 mg/l dye concentration were 63, 64 and 66%, respectively, and at the 100 mg/l dye concentration were 58, 32 and 41%, respectively. For the disazo dye, two color removal rates were evident, with the initial rate in the first two hours of the anaerobic stage higher than the latter. For the two anthraquinone dyes, only one rate of color removal was seen. For the oxazine dye, a high decolorization was observed in the reactor, but when disturbed, the color re-appeared for unexplainable reasons. The phosphorus removal efficiencies were 78, 52, 41 and 96% for the four dyes of 20 mg/l, respectively, while the corresponding numbers for the 100 mg/lcondition were 48, 48, 48 and 42%, respectively, and different types of dyes had different impacts on the phosphorus removal performance. COD and TKN removals were very high, i.e., 90–99 percent. The disazo reactive dye was decolorized by the reductive reaction, which resulted in the cleavage of the azo bond. Meanwhile, the decolorization of anthraquinone dyes is believed to be through the direct adsorption of dyes on to the floc materials.

Résumé :
In the current work we have investigated the ability of time-dependent density functional theory (TD-DFT) to predict the absorption spectra of a series of oxazine dyes and the effect of solvent on the accuracy of these predictions. Based on the results of this study, it is clear that for the series of oxazine dyes an accurate prediction of the excitation energy requires the inclusion of solvent. Implicit solvent included via a polarizable continuum approach was found to be sufficient in reproducing the excitation energies accurately in the majority of cases. Moreover, we found that the SMD solvent model, which is dependent on the full electron density of the solute without partitioning into partial charges, gave more reliable results for our systems relative to the conductor-like polarizable continuum model (CPCM), as implemented in Gaussian 09. In all cases the inclusion of solvent reduces the error in the predicted excitation energy to <0.3 eV and in the majority of cases to <0.1 eV.

Résumé :
Optical signal amplification in the waveguiding structure of optical fibers can be used for optical telecommunication systems and new light sources constructions. Organic dyes doped materials are interesting for new applications in polymeric optical fibers technology due to their benefits (efficient fluorescence, high absorption cross section, and easy processing). This article presents a numerical simulation of gain in poly(methyl methacrylate) optical fiber doped by Oxazine 170 Perchlorate. The calculated gain characteristic for the used dye molar concentration (0.2·10-6–1.4·10-6) and pump power (1–10 kW) is presented. The fabricated fluorescent polymeric optical fiber is also shown. The presented analysis can be used for optical amplifier construction based on dye-doped polymeric optical fiber (POF).

Résumé :
The cationic dyes rhodamine 6G (R6G) and oxazine 4 (Ox4) were intercalated into oriented lithium hectorite (LiHT, a synthetic fluor-mica) films by ion-exchange, and their orientation was studied by x-ray and polarized spectroscopy. Orientation of dyes was determined by basal spacing obtained by x-ray diffraction data, showing that angles of the long axis were 60° for R6G and 47° for Ox4 against the layer. Polarized ultraviolet-visible spectroscopy showed that the high-order H-aggregate of R6G and Ox4 were oriented at 64° and 52° against layers, respectively; other states of dyes were oriented at much lower angles. The interlayer distance was mostly determined by dimensions of the high-order H-aggregate.

Résumé :
Organic dyes namely 1,3,3-trimethylindolino-naphtospirooxazine (TINS) and 3,3-diphenyl-3H-napthol [2,1-pyran DNP) were used in studies of photochromic transformation in ethanol solution. The samples were exposed to UV light ranging from 5, 10 and 15s respectively. TINS absorbs UV light at 613nm for multiple exposure time. The absorption initiated the opening of oxazine spirostructure with formation of open merocyanine species. Irradiation of DNP with UV at 5, 10 and 15s absorbs at 413nm with formation of opening cyclicstucture of naphthopyran, namely allenyl-naphtol. The intensity peaks of TINS and DNP were increased with increasing the period of irradiation time. TINS and DNP dyes exhibit normal photochromic in the polar protic solvent by displaying color changes form transparent to color blue and light orange under exposed UV light. The photochromic activity of these compounds is due to the reversible light-induced cleavage of the C-O bond between the heterocyclic oxygen atom and the quaternary carbon.

Résumé :
AbstractThe effect of plasmon resonance of silver island films (SIF) on the interlayer Förster resonance energy transfer (FRET) between xanthene and oxazine dye molecules was studied. It has been shown that the enhancement of FRET can be controlled by changing in the distance between the donor-acceptor system and the SIF. The maximum increase in energy transfer efficiency (EET) by a factor of 2.6 was recorded at a distance of 6 nm from the SIF. The assumption was made that an increase in EET can be associated with both the direct appearance of a plasmon-enhanced rate constant of energy transfer and an increase in the quantum yield of the energy donor in direct contact with the SIF. The results can serve as a basis for studying of photoinduced processes in hybrid materials such as “organic dye-plasmon nanoparticles”, to increase the photosensitivity of solar cells in the visible region of the spectrum, and for the studying of photobiological processes, as well as to create materials with desired properties, sensors and light energy converters.

Résumé :
Fundamental quantitative studies of dyes (Nile Blue 690, Oxazine 725, Cresyl Violet 670) adsorbed to fused-silica surfaces were performed to determine the usefulness of multiresonant χ(2) spectroscopy as a surface-selective tool. Factors considered include laser-induced desorption, saturation of resonant transitions, choice of the most useful molecular resonances, molecular orientation, laser incidence angle, and laser polarization. In the most restrictive case (doubly resonant), elimination of desorption and saturation problems required laser power densities below 67 kW/cm2, while for a nonresonant case power densities of 2 GW/cm2 could be used. The resonant enhancement of χ(2) and limitations on usable power densities combine to yield similar detection limits for resonant and nonresonant studies. Detection limits of 0.037 to 0.17 monolayer were obtained for various multiresonant and nonresonant cases. The multiresonant case retains the important advantage of selecting a single mixture component for examination, as demonstrated by an initial study of an adsorbate mixture system.

Spiro [2H-indole-2,3'-[3H]naphth[2,1-b][1,4]oxazine],1,3-dihydro-1,3,3-trimethyl-6'-(1-piperidinyl) was incorporated onto polypropylene and photochromic polypropylene multifilaments produced through the mass coloration technique. Subsequently the polypropylene (PP) filaments were doped with a different concentration of photochromic pigment, and after producing the filaments different drawing ratios were applied. The photochromic colour build was found to be maximum with the highest concentration of dyes as well as with the lowest drawing ratio. Also the colour differences for L*, a*, b* and ΔE* were analysed with respect to the different concentrations and drawing ratios of the filament. The filaments generally showed good stability of photocoloration during the colour measurement till five cycles. The results for the optical density were reduced by increasing the fineness of the filament. In this experimental work, the impact of the drawing ratio on the optical and mechanical properties of these multifilaments were investigated.

Résumé :
Kauffman and Bentley [Laser Chem. 8, 49-59 (1988)] have reported increased laser output by changing the anion of certain pyridinium oxazole dyes from the tosylate to the mesylate salt. Likewise, zwitterion variants of these dyes are also reported to have a significantly improved laser output. We find anion changes to be modest and, with one exception, all zwitterions tested were no better or not as good as the tosylate salt with respect to lasing output. However, both the mesylate salt and the zwitterion variants have greatly improved lifetimes if there is no fluorine auxochrome in the basic dye. These authors also report observation of bifurcated lasing output curves. We see no such phenomena.
