Biyiklioglu, Mack published the artcilePi-stacking interaction perphenazine modified zinc(II) phthalocyanine nanoparticles for photothermal and photodynamic therapy, Quality Control of 91-15-6, the main research area is perphenazine zinc phthalocyanine nanoparticle photothermal photodynamic therapy.

Photodynamic therapy and photothermal therapy as non-invasive treatment methods have been receiving more and more attention. The report shows that zinc(II) phthalocyanine (Pc2) modified by perphenazine forms nanoparticles with a particle size of 110 nm by π-π stacking in water. It has good photothermal effect when illuminated by 680 nm laser in aqueous solution In addition, its ability to produce active oxygen is 2.3-fold that of methylene blue, so Pc2 also has a good photodynamic effect. In vivo fluorescence shows that Pc2 has a good targeting effect on tumors. Under the synergistic effect of photodynamic therapy and photothermal therapy, Pc2 has good tumor inhibition efficiency.

Zatsikha, Yuriy V. published the artcileDevelopment of a Class of Easily Scalable, Electron-Deficient, Core-Extended Benzo-Fused Azadipyrromethene Derivatives (“”MB-DIPY””), Product Details of C8H4N2, the main research area is benzofused azadipyrromethene derivative MBDIPY.

We have developed a new synthetic strategy for the preparation of a series of isoindolin-1-imines and isoindolin-1-ones from aromatic ketones and phthalonitrile. Self-condensation reactions of these isoindolin-1-imines led to the formation of a novel class of benzo-fused, highly electron-deficient core-extended azadipyrromethene chromophores (“”MB-DIPY””). The influence of temperature, catalyst, and the template ions on the self-condensation reaction rate, yield, and stereoselectivity was examined in detail. New chromophores (sodium, zinc, and metal-free compounds) were characterized by NMR, UV-vis, fluorescence, high-resolution mass spectroscopies, and in many cases, X-ray crystallog. Their redox properties were probed by electrochem. and spectroelectrochem. approaches that revealed the remarkable electron-accepting nature of the new systems. Stepwise one- and two-electron reduction of the new MB-DIPYs and their zinc complexes was investigated by spectroscopic and spectroelectrochem. methods. Both one- and two-electron reduced forms of all zinc complexes studied have strong absorption in the near-IR region up to âˆ?200 nm. Unusual spectroscopic and electrochem. properties of these dyes were correlated with their electronic structures and excited-state natures predicted by d. functional theory (DFT) and time-dependent DFT calculations Despite some structural similarities with well-known aza-BODIPYs, the new MB-DIPYs differ remarkably from them in spectroscopic and redox properties.

Janczak, Jan published the artcileThe synthesis, structure, and spectral properties of antimony(III) phthalocyanine obtained under iodine vapor atmosphere: (SbIIIPc)(I3) 1/2(I2), Safety of Phthalonitrile, the main research area is phthalonitrile reaction antimony iodine; antimony phthalocyanine iodine preparation crystal mol structure.

New antimony(III) phthalocyanine complex under iodine vapor atm., (SbIIIPc)(I3)·1/2(I2), (1), was obtained. The (SbIIIPc)(I3)·1/2(I2) crystallizes in the centrosym. space group of the triclinic system. The (SbPc)+ unit is non-planar Two inversion related (SbIIIPc)(I3) units interact each other via neutral I2 mol. yielding {[C32H16N8Sb](I3)}2(I2) dimeric aggregate. Resonance Raman spectroscopy was used to identification of the iodine forms in crystal. The aggregates related by translation in the direction of the a-axis form a stacking structure. However, within the stacks, the Pc rings are clearly shifted, so the π-π interactions is relatively very low, due to their non-planarity, as well as by only partial overlapping of the outermost six-membered rings of the adjacent back-to-back-oriented (SbPc)+ macrocycles. The interaction between the building units (SbPc)+, I-3 and I2 were analyzed using the Hirshfeld surface and the anal. of the 2D fingerprint plots. Relatively low interactions of π…π result in its considerable solubility, which manifests itself particularly in the improvement of optical properties of solutions UV-Vis absorption spectra of 1 were taken in DMSO and toluene solutions in the concentration range from 10-5 to 10-6 mol/l. No significant changes related to aggregation in solutions were observed Diffuse reflectance spectroscopy (DSR) due to interactions between the mols. in solid-state, showed much wider bands compared to the UV-Vis bands of the complex in solution Oxidation of (SbIIIPc)(I3)·1/2(I2) in methanol solution by H2O2 yields SbVPc derivative Both SbIII and SbV phthalocyanine derivatives absorb near IR light (600-900 nm) which should be intriguing with the point of view of potential use as an IR cut filter for plasma display and silicon photodiodes, and in addition to as photosensitizers for semiconductor lasers.

Mulholland, Katie D. published the artcileIridium-catalysed 3,5-bis-borylation of phthalonitrile enables access to a family of C4h octaarylphthalocyanines, Safety of Phthalonitrile, the main research area is transition metal octaarylphthalocyanine complex preparation crystal structure; NMR spectra fluorescence transition metal octaarylphthalocyanine complex; preparation arylphthalonitrile crystal structure NMR spectra.

Ir-catalyzed borylation of phthalonitrile produces both 4-(Bpin)phthalonitrile (1) and 3,5-bis(Bpin)phthalonitrile (2), which are potential divergent intermediates for the synthesis of functionalized phthalocyanines. To exemplify the utility of 2, the authors prepared a series of 3,5-bis-arylphthalonitriles that in turn undergo sterically controlled regioselective cyclotetramization to give previously unknown C4h 1,3,8,10,15,17,22,24-octaarylphthalocyanines.

Series of homoleptic and heteroleptic 3d transition metal complexes were prepared in anal. pure form and high yield, by reacting appropriate metal precursors with 1,3-bis(2-pyridylimino)isoindolate (BPIH) ligand under suitable reaction conditions. The complexes were characterized by various spectro-anal. techniques, including IR, UV, NMR, ESI Mass and x-ray crystal anal. A distorted octahedral structure containing two meridionally coordinating BPI ligands was assigned to all the homoleptic complexes. While, for the heteroleptic complexes, a highly distorted square pyramidal geometry, with a planar tridentate BPI ligand coordinating to the metal center along with chloro and aqua ligands was assigned. Considering the unique structural features of the complexes, potential catalytic applications are envisaged.

Moeini, Nazanin published the artcileSynthesis and characterization of magnetic Fe3O4@Creatinine@Zr nanoparticles as novel catalyst for the synthesis of 5-substituted 1H-tetrazoles in water and the selective oxidation of sulfides with classical and ultrasonic methods, Product Details of C8H4N2, the main research area is magnetic creatinine zirconium nanoparticle sulfoxidation cycloaddition catalyst sulfoxide tetrazole.

Tetrazoles and sulfoxide compounds have a wide range of applications in industries and are of great expectation to be environmentally friendly and cost-effective. This paper reports the introduction of zirconium supported on Fe3O4 nanoparticles through creatinine post-functionalization modification of Fe3O4 (Fe3O4@Creatinine@Zr). The Fe3O4@Creatinine@Zr was characterized by a vibrating sample magnetometer, X-ray powder diffractometry, Fourier transforms IR, scanning electron microscope, energy dispersive X-Ray anal., thermogravimetric anal., and inductively coupled plasma. Fourier transform-IR spectroscopy results confirmed that creatinine was successfully immobilized on the surface of Fe3O4-Cl with the presence of ν(C = N), and ν(C = O) bands of creatinine. X-ray diffraction data confirmed that the crystalline phase of Fe3O4 was not destroyed after modification. Vibrating sample magnetometer anal. showed that the saturation magnetization of the Fe3O4@Creatinine@Zr was 28.6 emu/g. The SEM-EDX results revealed that the zirconium complex was successfully incorporated into the structure of Fe3O4. This catalyst displayed high catalytic performance in the synthesis of 5-substituted 1H-tetrazoles and the selective oxidation of sulfides with classical and ultrasonic methods. The catalyst conferred strong Lewis’s acidity sites for the activity and selectivity of the reactions. The obtained results showed that the fast oxidation of sulfides occurred with 0.2 mmol g -1 of zirconium immobilized on the Fe3O4 nanoparticle at optimum condition (sulfide (1 mmol), H2O2 (0.6 mL), ethanol (3 mL) and catalyst (Fe3O4@Creatinine@Zr, 60 mg) at room temperature). The results showed that ultrasonic was an appropriate method for the oxidation of sulfides to the related sulfoxide at the optimum condition. The 5-substituted 1H-tetrazoles were afforded at optimum condition (nitrile (1 mmol), NaN3 (1.2 mmol), H2O (3 mL), catalyst (100 mg) at 90°C). The catalyst was separated by simple recovery and reused for seven cycles without any remarkable decrease in the catalysis activity and selectivity. The output of this research can open a window for the synthesis the other organic materials under mild condition.

To alleviate diffusion-limited photoinduced electron transfer (PET) in solution, a triphenylamine-derived dye and a Keggin polyoxometalate-type electron relay were coupled into a coordination polymer to photoinduce long-lived charge-separation pairs with enough reductive/oxidative potential to pump multiple electrons unidirectionally from external electron donors to acceptors, thus furnishing photocatalytic radical couplings to afford value-added α-amino C-H arylation products.

Hui, Heping published the artcileStructure characterization, antioxidant and hypoglycemic activity of an arabinogalactoglucan from Scutellaria baicalensis Georgi, Quality Control of 91-15-6, the main research area is Scutellaria arabinogalactoglucan SBP1 antioxidant hypoglycemic agent; Antioxidant and hypoglycemic activity; Arabinogalactoglucan; Scutellaria baicalensis Georgi; Structure characterization.

An arabinogalactoglucan SBP-1 was purified from Scutellaria baicalensis by DEAE-52 and Sephadex G-100 column chromatog. The structure of SBP-1 was characterized using HPLC, IR, GC-MS, 1-D and 2-D NMR. The antioxidant and hypoglycemic activity of SBP-1 was investigated by vitro evaluation. The results showed that SBP-1 was composed of arabinose, glucose and galactose in a molar ratio of 1.0:5.9:1.1 and its Mw were 91,156. The backbone of SBP-1 was mainly composed of repeating →1-α-D-Glcp-(4 → 1)-α-D-Glcp-(3 → 1)-α-D-Galp-(4→. The braches were composed of →2)-α-L-Araf-(1→, →3)-β-D-Glcp-1→ and α-D-Glcp-1→, which mainly substituted at O-6 of Glc, while terminal residue was α-L-Araf-1→ and α-D-Glcp-1→. Vitro bioactivity showed that SBP-1 had dose-dependent antioxidant and hypoglycemic activity. The scavenging rate on ABTS, DPPH, hydroxyl and superoxide radicals was all beyond 60% as SBP-1 concentration reached 4 mg/mL, and the inhibition rate on α-glucosidase and α-amylase was both more than 80%, which was closely to that of acarbose.
