Bonegardt, Dmitry published the artcileHybrid materials of carbon nanotubes with fluoroalkyl- and alkyl-substituted zinc phthalocyanines, COA of Formula: C8H4N2, the main research area is carbon nanotube fuoroalkyl alkylsubstituted zinc phthalocyanine morphol humidity.

In this work, hybrid materials of single-walled carbon nanotubes (SWCNT) noncovalently functionalized with fluoroalkyl- (SWCNT/ZnPc-CF) and alkyl- (SWCNT/ZnPc-CH) substituted zinc(II) phthalocyanines were prepared The effect of fluorination of the substituents in phthalocyanine macrocycle on the functionalization degree of carbon nanotubes and sensor response to ammonia was investigated. It was shown that the type of substituents in the phthalocyanine macrocycle showed noticeable effect both on the degree of functionalization of carbon nanotubes and on the sensing performance of the investigated hybrids. The amount of phthalocyanine mols. adsorbed on SWCNT walls was shown to be 1.5 times higher in the SWCNT/ZnPc-CH hybrid. The SWCNT/ZnPc-CF layer exhibited 2 times less chemiresistive sensor response to ammonia than SWCNT/ZnPc-CH, while its sensor response was more stable at 70% relative humidity.

Korkmaz, Aysun published the artcileAsymmetric phthalocyanines conjugated on silica for the photocatalytic degradation of organic pollutants synthesis, characterization and investigation of the photophysicochemical properties, SDS of cas: 91-15-6, the main research area is phthalocyanine silica organic pollutant photocatalytic degradation photophysicochem property.

A series of novel asym. metallo (Mg, Zn and Ga) phthalocyanines were synthesized using different ratios of starting materials. After purification, these compounds were obtained in high yields. The asym. phthalocyanines were characterized by UV-visible (UV-vis), IR (IR) and 1H NMR spectroscopy, mass spectrometry (MS) and elemental anal. High solubility in organic solvents was observed because of the ester moiety at the peripheral position, and no aggregation was observed over a wide concentration range. The photophysicochem. properties of magnesium (3a), zinc (3b) and gallium (3c) phthalocyanines were examined The highest singlet oxygen quantum yield of 0.66 was obtained for 3c. The photophysicochem. measurements demonstrate clearly the potential of these asym. phthalocyanines as photocatalytic agents in the photodegradation of organic pollutants in wastewaters. The zinc complex (3b) was attached onto silica as a solid support, and photocatalytic degradation studies were carried out using Orange G to provide a typical organic pollutant.

Guezel, Emre published the artcileHigh Photosensitized Singlet Oxygen Generating Zinc and Chloroindium Phthalocyanines Bearing (4-isopropylbenzyl)oxy Groups as Potential Agents for Photophysicochemical Applications, Category: nitriles-buliding-blocks, the main research area is oxygen zinc chloroindium phthalocyanine isopropylbenzyloxy photophysicochem application.

In this study, novel phthalonitrile derivatives (1 and 2) and their peripherally and non-peripherally tetra (4-isopropylbenzyl)oxy-substituted zinc and chloroindium phthalocyanine complexes (3-6) have been prepared for the first time. The synthesized phthalonitrile derivatives and phthalocyanine complexes were characterized spectroscopically. Not only the chloroindium phthalocyanines but also zinc phthalocyanines are essentially free from aggregation in THF at the studied micromolar concentration The purpose is to compare the effects of two types of substitution on the phthalocyanines to be used as sensitizers in photodynamic therapy (PDT). Photophys. and photochem. properties of all phthalocyanines are investigated and the results showed that the peripheral phthalocyanines more effectively photooxidize DPBF through singlet oxygen. The photochem. results showed that both ZnPc (3 and 5) and InPc (4 and 6) can be used as sensitizers in PDT because of their very high singlet oxygen quantum yields (range from 0.80 to 0.97).

Araghi, Mohammad Esmaeil Azim published the artcileThermal and Temporal Properties of a Thin Layer of Bromo Indium Phthalocyanine Nanostructures, Safety of Phthalonitrile, the main research area is bromo indium phthalocyanine nanostructure thermal temporal property.

In this work, we report on the synthesis, fabrication, and elec. and optical characterization of sandwich devices of bromo indium phthalocyanine thin film nanostructures in aluminum electrodes using electron beam evaporation in a high vacuum which have the potential to be used for sensing applications. The study investigate the influence of both parameters of temperature and frequency on the conduction mechanism to determine the transport process in the carriers. Results demonstrate that the capacitance, dielec. constant and loss factor decrease with increasing the frequency and increase in high temperatures The behavior of capacitance and loss factor fits well with the model of Goswami and Goswami and the results imply the domination of hopping theory. In addition, anal. of the absorption spectrum indicates that the optical band gap energy is 3 eV. Furthermore, morphol. anal. demonstrates that all films have a smooth surface with homogeneous small crystal grains with a nanoscale size order of 40 ± 10 nm. Thus, temperature and frequency-dependent experiments of optical and elec. parameters of the bromo indium phthalocyanine thin film nanostructures show their potential to be employed for sensing applications.

Tahershamsi, Leili published the artcileSynthesis, spectroscopic characterization and photoactivity of Zr(IV) phthalocyanines functionalized with aminobenzoic acids and their GO-based composites, Name: Phthalonitrile, the main research area is zirconium phthalocyanine photoactivity aminobenzoic acid graphite oxide composite.

Two complexes of bis(aminobenzoato)zirconium(IV) phthalocyanine and their graphite oxide-based composites were synthesized and characterized in respect of their photochem. properties. Structures of phthalocyanines were confirmed by Mass and IR spectroscopies. The absorption and photoluminescence spectra were investigated to show various behavior of the complexes in different media (DMSO and saline). Optical technique (monitoring variation of absorption spectra of diphenylisobenzofuran used as an indicator) was used to prove the generation of reactive oxygen species (ROS) by under light irradiation in the range of the first biol. window. The photoactivity of the materials was compared and discussed in terms of their potential ability to be used in biomedical applications, for example, as photosensitizers in photodynamic therapy.

Gounden, Denisha published the artcileMetallophthalocyanines in a ternary photoactive layer (P3HT:MPc:PC70BM) for bulk heterojunction solar cells, Synthetic Route of 91-15-6, the main research area is metallophthalocyanine PHT PCBM bulk heterojunction solar cell.

Novel bulk heterojunction (BHJ) organic photovoltaic (OPV) solar cells have been fabricated by introducing a series of metallophthalocyanines (MPcs) into a blend of a poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-Ph C70 butyric acid Me ester (PC70BM) photoactive layer. Sixteen MPcs have been synthesized with due consideration of the metal type and valency, functionalised ligand moieties and their resp. mol. energy levels. The MPcs were expected to act as an electron cascade material that improves the photovoltaic performance in a two-fold manner: first, to provide an efficient energy level offset between the polymeric donor (P3HT) and the fullerene-based derivative acceptor (PC70BM) to enhance charge transfer and reduce recombination within the OPV solar cells, and second, to harvest a greater portion of the solar spectrum as MPcs are associated with absorption near the near-IR region. BHJ OSCs were fabricated in the following inverted configuration: ITO/TiO2/P3HT:MPc:PC70BM/WO3/Ag and were investigated for their optimum photovoltaic performance. The BHJ OSCs comprising P3HT, PC70BM and the manganese MPc (MnPc) series photoactive layer displayed the best PCEs in the range of 2.36-2.62% which were approx. 47.5-63.7% higher than those of the binary reference BHJ OSCs.

Abdelhameed, Reda M. published the artcileBoosting the photocatalytic activity of Ti-MOF via emerging with metal phthalocyanine to degrade hazard textile pigments, Safety of Phthalonitrile, the main research area is metal phthalocyanine titanium photocatalytic activity textile pigment.

Metal-organic frameworks (MOFs) have shown a great potential for producing efficient and eco-friendly photocatalysts. Furthermore, phthalocyanines (PCs) are promising materials in photocatalytic reactions because of their unique adsorption and photosensitizing properties. Here, three phthalocyanines (Pcs) derivatives with Al3+ and Co2+ ions as the central metal were prepared to attach them to the MOFs matrix. The photocatalytic decay performance of methylene blue (MB) and methyl orange (MO) and their mixtures were investigated under visible light illumination. The photocatalyst NH2-MIL-125, Al-PcCl@NH2-MIL-125, CoPc@NH2-MIL-125, and CoPcPA@NH2-MIL-125 show 0.01, 0.012, 0.035, and 0.046 min-1 MB degradation rate, resp., while, the degradation rates of MO were 0.021, 0.027, 0.052 and 0.082, resp. Amazingly, the degradation rates of MB in presence of MO showed boosted photocatalytic decomposition with the degradation rate of 0.066, 0.069, 0.085, and 0.120 min-1, resp. This study illustrates a high performance for utilizing porous MOF-based materials not only as supports but as electron acceptors that enhance both photostability and photocatalytic activity.

Bayrak, Nilufer published the artcileStructure based design, synthesis, and evaluation of anti-CML activity of the quinolinequinones as LY83583 analogs, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is quinolinequinone LY analog antichronic myelogenous leukemia activity; Aminoquinone; Apoptosis; Chronic myelogenous leukemia (CML); DNA-Cleavage; LY83583; Quinolinequinones; Structure-activity relationship (SAR).

Quinone-based small mols. are the promising structures for antiproliferative drug design and can induce apoptosis in cancer cells. Among them, one of the quinolinequinones, named as 6-anilino-5,8-quinolinequinone, LY83583 has the ability to inhibit the growth of cancer cells as an inhibitor of cyclase. The biol. potential of all synthesized compounds as the analogs of the identified lead mol. LY83583 that possessed the antiproliferative efficiency was determined The two series of the LY83583 analogs containing electron-withdrawing or electron-donating group(s) were synthesized and subsequently in vitro evaluated for their cytotoxic activity against K562, Jurkat, MT-2, and HeLa cell lines using MTT assay. All the LY83583 analogs showed antiproliferative activity with good IC50 values (less than pos. control imatinib). Four analogs from each series were also selected for the determination of selectivity against human peripheral blood mononuclear cells (PBMCs). The analog AQQ15 showed high potency towards all cancer cell lines with almost similar selectivity of imatinib. In order to get a better insight into cytotoxic effects of the analog AQQ15 in K562 cells, further apoptotic effects due to annexin V/ethidium homodimer III staining, ABL1 kinase inhibition, and DNA cleaving ability were examined The analog AQQ15 induced apoptotic cell death in K562 cells with 34.6% compared to imatinib (6.5%). This analog showed no considerable ABL1 kinase inhibitory activity but significant DNA cleavage activity indicating DNA fragmentation-induced apoptosis. Besides, mol. docking studies revealed that the analog AQQ15 established proper interactions with the deoxyribose sugar attached with the nucleobases adenine and guanidine resp., in the minor groove of the double helix of DNA. In silico predicted pharmacokinetic parameters of this analog were found to comply with the standard range making it an efficient anticancer drug candidate for further research.

Rocker, Johannes published the artcileAlternatives to Iridium: A Polyaza[7]helicene as a Strongly Reductive Visible Light Photoredox Catalyst, Name: Picolinonitrile, the main research area is poly azahelicene photo redox catalyst.

The use of a readily accessible polyazahelicene as a strongly reducing metal-free alternative to the commonly used precious metal based photo redox catalysts is demonstrated. An improved two-step synthesis of the catalyst is described, and its photophys. properties with respect to its use as a photo redox catalyst are evaluated. Its activity under visible light irradiation is proven by application in two double radical light-driven multi-component reactions. The azahelicene gave comparable results to an iridium-based catalyst originally used for the same transformations.

Ishikawa, Yuta published the artcileRed-light-activatable ruthenium phthalocyanine catalysts, Name: Phthalonitrile, the main research area is ruthenium phthalocyanine red light activatable catalyst.

Phthalocyanine ruthenium complexes were identified as red-light activatable catalysts for trifluoromethylation reactions. The red-light mediated chlorotrifluoromethylation of alkenes could proceed without any sacrificial reducing reagents. This reaction exhibited good compatibility with a blue-light-absorbing substrate, while under irradation with blue light, i.e., under traditional photoreaction conditions, this substrate decomposed completely.
