Tong, Yue published the artcilePhotocatalytic redox-neutral arylation of cyclopropanols with cyanoarenes via radical-mediated C-C and C-CN bond cleavage, Recommanded Product: Phthalonitrile, the main research area is cyclopropanol cyanoarene bond cleavage photocatalytic redox neutral arylation.

β-Arylated ketones widely exist in many biol. active mols. and natural products. Herein, we describe a photocatalytic redox-neutral arylation of cyclopropanols with cyanoarenes via radical-mediated C-C and C-CN bond cleavage to afford various β-arylated ketones. This mild and external oxidant-free approach showed good compatibility with a range of cyclopropanols and cyanoarenes and accomplished absolute regioselective control for the precise functionalization of pyridines via the C-CN bond cleavage of 4-cyanopyridines. Remarkably, this photocatalytic ring-opening of cyclopropanols was enabled by proton-coupled electron transfer (PCET) activation using an oxidized photocatalyst.

Medjahed, Aboubakr published the artcileProcessability and mechanical properties of surface-modified glass-fibres/phthalonitrile composite and Al-Li alloy fibre-metal-laminates, Formula: C8H4N2, the main research area is glass fiber phthalonitrile aluminum lithium alloy mech property; glass phthalonitrile fiber metal laminate aluminum lithium alloy.

In this study, newly developed fiber-metal laminates (Al-LiFMLs) were prepared by a lay-up process of a high-performance surface-modified glass fibers/phthalonitrile (GFs/PN) composite and Al-Li alloy. The results showed that varying the composite considerably affected the tensile properties of the Al-LiFMLs, as well as exhibiting enhancements over the properties of both the individual Al-Li alloys and GFs/PN composite constituents. For instance, when the number of composite layers varied from 6 to 14, the ultimate tensile strength of the Al-LiFMLs increased from 315 to 611 MPa. It was revealed that the failure mode displayed a more ductile behavior (up to 20%) for all the developed Al-LiFMLs affected by the ductile fracture mode of the Al-Li alloy.

Mapukata, Sivuyisiwe published the artcileThe photocatalytic properties of zinc phthalocyanines supported on hematite nanofibers for use against methyl orange and Staphylococcus aureus, Computed Properties of 91-15-6, the main research area is photocatalytic property zinc phthalocyanin hematite nanofiber methyl orange; Staphylococcus aureus.

Heterogeneous photocatalysis is a promising approach for environmental remediation from contaminants including microorganisms and organic pollutants. In this work, hematite nanofibers are fabricated and modified with a novel monosubstituted Pc (4) as well as an asym. tetrasubstituted Pc (5) with the aim of creating hybrid photocataysts. The photocatalytic activities of the unmodified and phthalocyanine modified hematite nanofibers were compared based on their efficiencies in the photoinactivation of S. aureus and photooxidation of methyl orange. For both applications, the hybrid nanofibers were found to be more efficient photocatalysts than the unmodified hematite nanofibers. Comparison of the modified nanofibers (4-Fe2O3 and 5-Fe2O3) showed that they have comparable antibacterial activity while the 5-Fe2O3 nanofibers are the best for the photooxidation of methyl orange. The singlet oxygen generation efficiency, high activity, versatility, regenerability and thus reusability of the fabricated hybrid nanofibers makes them ideal candidates for real life water treatment studies.

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.

Gao, Jing published the artcileTheoretical search of a simple characteristic for long-lived organic room-temperature phosphorescence materials with H aggregation, Safety of Phthalonitrile, the main research area is thioxanthone derivative hydrogen aggregation room temperature phosphorescence.

Recently, more and more room temperature phosphorescent (RTP) phenomena have been observed in crystals and organic aggregates, which indicates the dependence of RTP luminescence properties on the mol. packing patterns. At present, an important kind of reported RTP material are those possessing H-aggregation, which is considered to suppress fluorescence and improve the lifetime of excited triplet states. Herein, we tried to find a simple characteristic for H-aggregated RTP materials through exploring the processes of electron transition and energy transfer of the dimers in H-aggregation. An interesting phenomenon aroused our interest, i.e., the overlapping area between H-aggregated dimers exhibits strong correlation with the phys. parameters characterizing the RTP performance, such as the number of ISC channels, the spin-orbital coupling (SOC) value, the oscillator strengths of singlet states, the energy transfer rate between the triplet states, and the final RTP lifetime. The scanning of the intermol. relative position shows that an overlapping area within 40-60% could prolong the phosphorescence lifetime, which could be further proved by other H-aggregated crystals. This exploration not only highlights the important role of the overlapping area in characterizing the phosphorescence lifetime, but also provides guidance for developing persistent pure organic RTP materials.

Meerovich, G. A. published the artcileNovel Polycationic Photosensitizers for Antibacterial Photodynamic Therapy, Name: Phthalonitrile, the main research area is polycationic photosensitizer antibacterial photodynamic therapy; Aggregation; Antibacterial photodynamic therapy; cationic photosensitizer; Bacterial biofilms; Bacteriochlorins; Luminescence.

Antibacterial photodynamic therapy (APDT) is a promising method of treating local infected foci, in particular, surgical and burn wounds, trophic and diabetic ulcers. Photodynamic inactivation (PDI) is able to effectively destroy bacterial cells without them developing resistance in response to treatment. This work was dedicated to the study of photophys. and antibacterial properties of new photosensitizers (PS) based on polycationic phthalocyanines and synthetic bacteriochlorins for photodynamic inactivation of P. aeruginosa bacteria and their biofilms. Gram-neg. bacteria P. aeruginosa are often found in infected wounds, presumably in biofilm state and are characterized by rather low susceptibility to APDT, which is a problem. PS were studied for possible aggregation at various concentrations by means of absorption and fluorescence spectroscopy. The results of studies of the ZnPcChol8, (3-PyHp)4BCBr4 and (3-PyEBr)4BCBr4 in water and serum confirm the assumption of a low degree of their aggregation at high concentrations Consequently, their photodynamic efficiency is high enabling to use these PS at high concentrations to sensitize pathol. foci for APDT. It was shown that all the investigated PS had a high efficiency of photodynamic inactivation of Gram-neg. bacteria P. aeruginosa, as well as their biofilms. Tetracationic hydrophilic near-IR photosensitizer (3-PyEBr)4BCBr4 with reduced mol. size had significantly higher efficacy of photodynamic inactivation of P. aeruginosa biofilms compared with other studied photosensitizers.

Zatsikha, Yuriy V. published the artcileβ-Isoindigo-azaDIPYs: Fully Conjugated Hybrid Systems with Broad Absorption in the Visible Region, Application of Phthalonitrile, the main research area is isoindigo azaDIPYs conjugated hybrid system broad absorption visible region; 1-imino-3-thioisoindolines; BODIPY; density functional calculations; fused-ring systems; β-isoindigo.

A one-step synthetic pathway for the preparation of fully conjugated β-isoindigo-azaDIPY hybrid chromophores comprised of β-isoindigo and azadipyrromethene moieties is reported. The target compounds were characterized by spectroscopic, crystallog., and theor. methods and show unprecedented broad absorption across the visible region of the electromagnetic spectrum. The x-ray crystal structure of the octa(n-butyl)-β-isoindigo-azaDIPY derivative revealed that a trans-configuration of the β-isoindigo fragment accompanies a planar conjugated core.
