Methylammonium iodo bismuthate perovskite (CH3NH3)(3)Bi2I9 as new effective visible light-responsive photocatalyst for degradation of environment pollutants

In this work, the photocatalytic activity of a new visible light-responsive (CIH3NH3)(3)Bi2I9 hybrid organic-inorganic perovskite (HOIP) was addressed for the very first time in the treatment of aqueous solutions of model organic dyes. The photocatalyst was successfully prepared by a low temperature solvo-termal method, easily reproducible. The catalyst was characterized by Fourier-transform infrared spectroscopy (FP-IR), X-ray diffraction spectrometer (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDS), X-ray photoelectron spectroscopy (XPS) techniques and UV diffuse reflectance spectrum. The efficiency of photocatalyst was tested for the removal of different type of dyes: fluorone dye (rhodamine B), thiazine dye (methylene blue) and azo dye (reactive Blue 4). Moreover, a multi-contaminated solution, with methylene blue and crystal violet (triarylmethane dye), was used to simulate a real industrial wastewater effluent. The results highlighted an increase of the photocatalytic activity respect the pristine precursor, bismuth iodide. The experiments showed that the values of removal was higher for rhodamine B respect the other dyes, with a removal of 98% after three hours under visible light irradiation. The efficiency of the photocatalyst was also confirmed under optimal conditions with high pressure liquid chromatography (HPLC). The gradual disappearance of rhodamine B peak accompanied by the appearance of by-products peaks was investigated. The stability of the photocatalyst was tested for three consecutive re-cycles. Analysis on different visible light sources was performed: halogen provided higher efficiency respect LED lamp. The outcomes of the present work aim to open the possibility of considering HOIP as a new potential photocatalyst for contaminants treatment.

Unexpected Products from Mesoionic 1,3-Thiazinium and Oxazinium Olates: A Novel Access to 3,5-Diaryl-1,3-thiazine-2,4,6-trione and Alkoxy-3,5-diphenyl-3H-1,3-oxazine-2,6-dione Derivatives

The condensation of (chlorocarbonyl)ketenes 1 with N-phenylthiocarbamates 2 and N-phenylcarbamates 6 is postulated to lead to the formation of unstable mesoionic 1,3-thiazinium 4-olates I or 1,3-oxazinium 4-olates II, respectively. At room temperature, appropriately substituted mesoionic 1,3-thiazinium 4-olates I eliminated the corresponding alkene with generation of 3,5-diaryl-1,3-thiazine-2,4,6-trione derivatives 3. However, the methoxy-substituted compound 5 was stable at room temperature at least for several weeks. In the case of the mesoionic1,3-oxazinium 4-olates II an alkyl group migration affords 4-alkoxy-3,5-diphenyl-3H-1,3-oxazine-2,6-diones 7.

Synthesis, spectroscopic structure identification, X-ray study and anticancer activities of new angularly fused quinobenzothiazines

Synthesis of 16 new tetracyclic angularly fused azaphenothiazines, 8-, 9- and 10-substituted quinobenzo1,4-thiazines (benzo[a]-3-azaphenothiazines) was based on the reactions of dichlorodiquinolinyl disulfide and diquinodithiin with substituted anilines. Whereas the reactions with p-fiuoroaniline and p-methylthioaniline led to only one product, the reaction with m-triflouromethylaniline led to isomeric compounds. The obtained 8-10-substituted 12H-quinobenzothiazines were further transformed into 12 substituted derivatives through allcylation of the thiazine nitrogen atom. The structure analysis was based on 1D and 2D NMR (NOESY, COSY, HSQC and HMBC) spectra which enabled to distinguish the isomers and to exclude retro-Smiles rearrangement and the azine nitrogen atom alkylation pathways. This supposition was fully confirmed by X-ray analysis showing the quinobenzothiazine system to be folded and the substituent at the thiazine nitrogen atom in an equatorial position. Some compounds exhibited anticancer activity against MCF-7, MDA-MB-231 and SNB-19 cell lines similar to a reference drug cisplatin. The structure-activity relationship of the compounds were discussed. (C) 2016 Elsevier B.V. All rights reserved.

10H-1,9-diazaphenothiazine and its 10-derivatives: synthesis, characterisation and biological evaluation as potential anticancer agents

10H-1,9-diazaphenothiazine was obtained in the sulphurisation reaction of diphenylamine with elemental sulphur and transformed into new 10-substituted derivatives, containing alkyl and dialkylaminoalkyl groups at the thiazine nitrogen atom. The 1,9-diazaphenothiazine ring system was identified with advanced H-1 and C-13 NMR techniques (COSY, NOESY, HSQC and HMBC) and confirmed by X-ray diffraction analysis of the methyl derivative. The compounds exhibited significant anticancer activities against the human glioblastoma SNB-19, melanoma C-32 and breast cancer MDA-MB-231 cell lines. The most active 1,9-diazaphenothiazines were the derivatives with the propynyl and N, N-diethylaminoethyl groups being more potent than cisplatin. For those two compounds, the expression of H3, TP53, CDKN1A, BCL-2 and BAX genes was detected by the RT-QPCR method. The proteome profiling study showed the most probable compound action on SNB-19 cells through the intrinsic mitochondrial pathway of apoptosis. The 1,9-diazaphenotiazine system seems to be more potent than known isomeric ones (1,6-diaza-, 1,8-diaza-, 2,7-diaza- and 3,6-diazaphenothiazine). [GRAPHICS] .

A comparative study for removal of different dyes over M/TiO2 (M = Cu, Ni, Co, Fe, Mn and Cr) photocatalysts under visible light irradiation

The purpose of this work is to design and develop a series of stable and effective TiO2 photocatalysts prepared by a modified precipitation method. In order to improve the photo response of the TiO2 to the visible region, the effect of addition of six successive transition metal elements of fourth period, namely chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), and copper (Cu) was studied. Two different types of dyes, methyl orange (MO, azo dye) and methylene blue (MB, thiazine dye group), were used to investigate the influence of structure of dyes on the photocatalytic degradation rates. The results showed that loading titania with 0.3 wt.% of different transition metal elements was found to have significant influences on the crystallographic structure, physical properties and optical absorption properties of titania based catalysts, as well as catalytic activity during dye degradation reactions. The optical reflection edge was obviously shifted to the visible light range with the transition metal additives. The band gap energies of the doped TiO2 samples were considerably narrower than that of plain TiO2. The different activity levels of the catalysts for both dyes clearly show that the photocatalytic activity of samples strongly depended on the metal dopant used. Among all the catalysts, Cu/TiO2 sample exhibited the highest photocatalytic activity under visible light for both of the dyes owing to the low band gap energy and delayed electron-hole recombination.

Protonation-State-Driven Photophysics in Phenothiazinium Dyes: Intersystem Crossing and Singlet-Oxygen Production

The impact of altering the solvent pH value on the photodynamic activity of thionine has been studied computationally by means of density functional theory and multi-reference interaction methods. To this end, we have investigated the electronic structure of the ground and excited states of diprotonated (TH22+) and neutral imine (T) forms of thionine (TH+). It is well known experimentally that the T-1 state of TH+ undergoes acid-base equilibrium reactions resulting in a pronounced pH effect for the efficiency of singlet-oxygen (O-1(2)) production. Our results show that the energy-transfer reactions from the T-1 state of TH22+ and T to O-3(2) correspond to reversible equilibrium processes, whereas in TH+ this process is very exothermic in a vacuum (-0.66 eV) and in aqueous solution (-0.49 eV). These facts explain the experimental observation of a much smaller efficiency of O-1(2) production for TH22+ than for TH+. Moreover, we found that the pH value significantly effected the intersystem crossing (ISC) kinetics impacting the concentration of triplet-state species available for energy transfer. In very acidic aqueous solution (pH < 2) where TH22+ is the prevailing species, the ISC proceeds with a rate constant of approximate to 10(8) s(-1). In a basic medium where T is the dominant species, ISC decay occurs by means of a thermally activated channel (approximate to 10(8)s(-1)) which competes with fluorescence (5.32 x 10(7) s(-1)). According to these results, maximum ISC efficiency is expected for intermediate acidic pH values (TH+, approximate to 10(9) s(-1)).
