Gumrukcu, Selin published the artcileIn-situ synthesis of phthalocyanines on electrospun TiO2 nanofiber by solvothermal process for photocatalytic degradation of methylene blue, Recommanded Product: Phthalonitrile, the main research area is phthalocyanine electrospun titanium dioxide nanofiber methylene blue photocatalytic degradation.

Titanium dioxide/phthalocyanine (TiO2/Pc), TiO2/fluor containing phthalocyanine (TiO2/FPc), and TiO2/fluor containing cobalt phthalocyanine (TiO2/FCoPc) had been successfully fabricated by a simple combination of phthalocyanines obtained by insitu synthesis on the surface of TiO2 nanofibers prepared by electrospinning. SEM micrographs and X-ray diffraction anal. indicated that the phthalocyanines uniformly immobilized on the surface of TiO2 nanofibers. Photocatalytic activity of TiO2, TiO2/Pc, TiO2/FPc, TiO2/FCoPc nanofibers for methylene blue in water was comparatively investigated firstly by ultravioletvisible absorption measurements with time, and kinetic parameters were calculated Results indicated that the obtained TiO2/Pc, TiO2/ FPc and TiO2/FCoPc exhibited high photocatalytic activity for the degradation of methylene blue and TiO2/FCoPc was found the best. It showed similar or higher activities than related studies and can be suggested as a promising candidate for environmental and energy applications.

Chan, Joseph Y. M. published the artcile[3 + 1] Mixed Cyclization: A Synthetic Route to Prepare Low-Symmetry Phthalocyanines, HPLC of Formula: 91-15-6, the main research area is zinc phthalocyanine nanoparticle preparation; base promoted cyclization trisphthalonitrile metal template.

A novel synthetic strategy for low-symmetry phthalocyanines was developed, which involves the base-promoted cyclization of a preconnected trisphthalonitrile and a free phthalonitrile in the presence of a metal template. By using this [3 + 1] mixed cyclization approach, a series of zinc(II) phthalocyanine derivatives were synthesized in up to 12% yields, including a very rare ABCD-type phthalocyanine and an amphiphilic ABAC-type analog that can self-assemble in aqueous media, forming stable spherical nanoparticles.

Zatsikha, Yuriy V. published the artcileEnvironmentally Benign Route for Scalable Preparation of 1-Imino-3-thioisoindolines-The Key Building Blocks for the Synthesis of Dithio- and Diamino-β-isoindigo Derivatives, COA of Formula: C8H4N2, the main research area is imino thioisoindoline synthesis; dithio diamino beta isoindigo derivative synthesis.

A one-step, gram-scale protocol for the preparation of 1-imino-3-thioisoindolines and a novel one-pot two-step methodol. of the synthesis of dithio- or diamino-β-isoindigo derivatives starting from phthalonitriles and sodium hydrosulfide in an aprotic dipolar solvent have been developed. It was demonstrated that the electronic properties of the substituent(s) in the phthalonitrile core play a critical role in β-isoindigo synthesis resulting either in the selective formation of dithio- or diamino-β-isoindigo chromophores. The N-acylated 1-imino-3-thioisoindolines can be used for the direct, easily scalable, and chromatog.-free procedure for the preparation of a new class of N,N’-diacylamino-β-isoindigoid compounds Properties of the monomeric as well as J-aggregated forms of dithio- and diamino-β-isoindigo were probed by the absorption and fluorescence spectroscopies. It was demonstrated that the tetracyano-diamino-β-isoindigo 3f can form a J-aggregate that absorbs at 793 nm and fluoresces at 824 nm. This aggregate is stable in N,N-dimethylformamide solution; however, it slowly dissociates in THF or under sonication conditions. D. functional theory (DFT) and time-dependent DFT (TDDFT) calculations were employed to elucidate the electronic structures, spectroscopic properties, and aggregation of new dithio- and diamino-β-isoindigo derivatives

Olgun, Ugursoy published the artcileNano-gold-based synthesis, characterization and band gap energies of gold(III)-2(3)-tetrakis(allyloxy)-substituted phthalocyanine and gold(III)-phthalocyanine dyes, Quality Control of 91-15-6, the main research area is gold tetrakis allyloxy phthalocyanine band gap oxidation.

In this study, we have attempted to synthesize Au (III)-phthalocyanine (Au-Pc) and Au (III)-2 (3)-tetrakis (allyloxy) phthalocyanine (Au-AoPc) by using phthalonitrile (Pn), 3 allyloxy-substituted phthalonitrile (Ao-Pn) and gold nanoparticles (AuNPs) as the starting materials. The N,N′-dimethyl amino ethanol (DMAE)-stabilized AuNPs were prepared from the HAuCl4 solution The purple color AuNPs were obtained by the reduction of HAuCl4 solution by the addition of DMAE and adjusting pH 6-7 at room temperature Then, the blue color Au-Pc and the green color Au-AoPc dye materials were synthesized at 120 °C temperature by the reactions of the AuNPs with Pn and AoPn. The obtained AuNPs, Au-Pc and Au-AoPc complexes were characterized using optical microscopy, transmission electron microscopy (TEM), UV-Vis absorption, FT-IR and electrospray ionization-mass spectrometry. The TEM anal. results showed that the sizes of AuNPs were mostly 30-40 nm and distributed within the range of 10-100 nm. By using the Tauc method, the optical band gap energies (Eg) were calculated as 1.66 eV for the Q-band and 3.12 eV for the B-band of the Au-Pc, and as 1.79 eV for the Q-band and 3.32 eV for the B-band of the Au-AoPc. The DMAE-stabilized AuNPs, the Au-Pc and the soluble Au-AoPc dyes with low band gap energy can be utilized for various technologies in electronics, imaging, sensors and solar cells.

Bhatia, Harsh published the artcileAsymmetric-donor (D2D2)-acceptor (A) conjugates for simultaneously accessing intrinsic blue-RTP and blue-TADF, Formula: C8H4N2, the main research area is donor acceptor photoluminescent room temperature phosphorescence.

The development of new photoluminescent (PL) materials with simultaneous room-temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) features is highly desirable for bio-imaging, security applications and sensors due to the involvement of both singlet and longer-lived triplet states. Here, we report two carbazolyl-phenoxy-phthalonitrile conjugates (CPPN, CPPNF). Spectroscopic studies combining two daughter compounds (PPN, PPNF) in polar and nonpolar hosts confirmed efficient blue-RTP from the higher-energy triplet state (TPPN) due to the phenoxy-phthalonitrile (PPN) part, and blue-TADF via reverse intersystem crossing from the low-lying triplet state (TCzPN) of the carbazolyl-phthalonitrile (CzPN) part to the singlet (S1) state of the same CzPN part, utilizing the TPPN state that acts as an intermediate for spin-vibronic coupling. Such PL characteristics are observed due to the energetic proximity of 3LEPPN, 1CTCzPN and 3CTCzPN. In the hydrogen-bonded matrix and crystals, we found faint persistent green-RTP characteristics of the PPNF due to supramol. interactions and aggregation of the mol. This study could pave the way to understanding the involvement of different excited states associated with TADF and RTP processes of asym.-donor-acceptor systems.

Wang, Wenzhi published the artcileMethoxypolyethylene Glycol-Substituted Zinc Phthalocyanines for Multiple Tumor-Selective Fluorescence Imaging and Photodynamic Therapy, Computed Properties of 91-15-6, the main research area is photodynamic therapy fluorescence imaging pharmacokinetics.

Highly tumor-tissue-selective drugs are a prerequisite for accurate diagnosis and efficient photodynamic therapy (PDT) of tumors, but the currently used fluorescent dyes and photosensitizers generally lack the ability for high accumulation and precise localization in tumor tissues. Here we report that monomethoxy polyethylene glycol (MPEG)-modified zinc phthalocyanine (ZnPc) can be selectively accumulated in multiple tumor tissues, and that the selectivity is controlled by the chain length of MPEG. MPEG-monosubstituted ZnPcs with different chain lengths were synthesized, among which the shorter chain (mw < 2k)-modified ZnPc did not show tumor tissue selectivity, while MPEG2k-5k-substituted ZnPc could be rapidly and selectively accumulated in H22 tumor tissues in mice after i.v. injection. Especially, MPEG4k-Pc showed the best tumor tissue selectivity with a tumor/liver (T/L) ratio of 1.7-2.2 in HepG2, MDA-MB231, AGS, and HT-29 tumor-bearing mice. It also exhibited potent photodynamic therapy effects after one PDT treatment, and tumor growth was significantly inhibited in H22-bearing mice with an inhibition rate over 98% and no obvious toxicity. Consequently, MPEG-modified ZnPc could serve as a potential platform for selective fluorescence imaging and photodynamic therapy of multiple tumors.

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.

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.

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.

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).
