Preparation of pH Responsive Polystyrene and Polyvinyl Pyridine Nanospheres Stabilized by Mickering Microgel Emulsions

New pH-sensitive polystyrene, PS, and poly(4-vinylpyridine), P4-VP, nanospheres were prepared by using surfactant-free method based on soft microgels (Mickering emulsion). The formation of stable Mickering cyclohexane/water emulsions was investigated by using soft microgel particles of poly(acrylamide), PAAm, poly(2-acrylamido-2-methylpropane sulfonic acid), PAMPS, and sodium salt of PAMPS, PAMPS-Na, as stabilizers. The dynamic light scattering (DLS), optical microscopy, and scanning electron microscopy (SEM) were used to investigate the optimum conditions and effects of surrounding solutions on the microgels characteristics and their corresponding Mickering emulsions. The cyclohexane/water Mickering emulsions stabilized by softer and neutral charged microgels were considerably more stable under the same conditions. Furthermore, the stimuli-responsive properties of PAMPS microgel stabilized cyclohexane/water Mickering emulsions suggest the potential utility in the preparation of PS and P4-VP nanospheres. The effects of pH changes on the morphology, particle sizes, and surface charges of PS and P4-VP microgels were evaluated to prove the pH-sensitivity of the prepared nanospheres.

A rotating disk electrode study on catalytic activity of iron(II) phthalocyanine-modified electrodes for oxygen reduction in acidic media

Catalytic activity of monometric metal macrocycles for oxygen reduction reaction (ORR) was investigated using rotating disk electrode voltammetry in acidic media. Iron(II) phthalocyanines (FePc) and cobalt(II) tetraphenylporphyrins (CoTPP) were immobilized on Au surfaces through molecular wires with different terminal groups of pyridine and isocyanide. The measured ORR behavior of FePc was largely influenced by the axial ligand while CoTPP promoted only the two-electron reaction regardless of the axial ligand. The FePc immobilized with pyridine was easily detached from the surface under the ORR condition, and was able to promote the four-electron reaction only under the high overpotential application. The FePc with isocyanide was more stable with the activity for the four-electron reaction, due to stronger electron donation to Fe central ions.

Synthesis and Antimicrobial Screening of Novel Azetidin-2-ones Derived from Pyromellitic Diimide via [2+2]-Cycloaddition Reaction

A series of novel 2-azetidinone derivatives have been obtained starting from pyromellitic dianhydride. Pyromellitic dianhydride was converted to pyromellitic diimide using sodium cyanate, and the diimide was alkylated with ethyl chloroacetate. The resulting diester was treated with hydrazine hydrate to obtain dihydrazide which reacted with substituted pyridine-2-carbaldehydes to give the corresponding Schiff bases, and [2+2]-cycloaddition of the latter with chloroacetyl chloride in the presence of triethylamine afforded the target azetidin-2-one derivatives. The newly synthesized compounds showed high antimicrobial activities against some bacterial and fungal strains.

Dye-sensitized solar cells using silicon phthalocyanine photosensitizers with pyridine anchor: Preparation, evaluation of photophysical, electrochemical, and photovoltaic properties

In this study, novel two silicon phthalocyanine photosensitizers (3PY-Si and 4PY-Si) containing pyridine groups as an electron-withdrawing and anchoring group have been prepared and chemically characterized for dye-sensitized solar cells (DSSCs). Photoelectrochemical and photovoltaic properties of the photosensitizers were evaluated. The new photosensitizers elucidated by spectroscopic and electrochemical techniques. As reported by fluorescence measurements, the silicon phthalocyanine photosensitizers exhibited slightly higher fluorescence quantum yield (phi(F) = 0.25) than the unsubstituted zinc phthalocyanine which is favorable for photophysical applications. The DSSC based on complex 3PY-Si shows the highest power conversion efficiency (PCE) of 0.53% with the J(sc), V-oc and FF values of 1.205 mA cm(-2), 0.612 V, and 0.72, respectively, in the presence of the coadsorbent. These silicon phthalocyanine photosensitizers with bulky axial pyridine substituents found to be important materials for (DSSCs) since they show strong absorption in the red region and their ligands hamper the stacking of rings. This situation prevented the formation of aggregates with a common tendency to photosensitizers on the TiO2 surface.

Synthesis of high molar extinction coefficient push-pull tricyanofuran-based disperse dyes: Biological activity and dyeing performance

Several push-pull tricyanofuran-based disperse dyes with high molar extinction coefficient were synthesized and fully characterized. The dyes were prepared via Knoevenagel reaction in dry pyridine under ambient conditions employing acetic acid as catalyst. The condensation process was carried out between the reactive methyl-bearing tricyanofuran moiety and tertiary amine-based arylaldehyde. The molecular structures of the synthesized chromophores were proved by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (H-1 and C-13 NMR) and elemental analysis (C, H, N). The UV-Vis absorbance spectra of the synthesized dyes demonstrated interesting extinction coefficient values, which were found to be influenced by the aromatic-vinyl bridge and the tertiary amine donor group bonded to this aromatic-vinyl bridge moiety. The prepared tricyanofuran-based disperse colorants were dyed on polyester fabrics to afford satisfactory results. The substituents attached to the tertiary amine moiety influenced the absorption maxima. The fastness properties of the dyed polyester samples were measured. The biological activities of the synthesized dyestuffs against fungus (Candida Albican) as well as Gram-positive (S. Aureus) and Gram-negative (E. Coli) pathogens were also evaluated.

Protic/aprotic ionic liquids for effective CO2 separation using supported ionic liquid membrane

Four ionic liquids (ILs) namely, 1-butylsulfonate-3-methylimidazolium P-toluene sulfonate ([BSmim][tos]), 1-butylsulfonate pyridine P-toluene sulfonate ([BSmpy][tos]), 1-butyl-3-methylimidazolium chloride aBmim][Cl]) and 1-butylpyridine chloride ([Bpy][Cl]) were synthesized for the effective separation of gases CO2/N-2 and CO2/CH4 through supported ionic liquid membranes (SILMs). ILs were confirmed by NMR and FTIR spectroscopy, and their characteristics and physical properties were studied. The ILs were immobilized on the porous hydrophobic 200 um thick polyvinylidene difluoride (PVDF) support. Pure and mixed gas separation performances of the prepared SILMs were analyzed in a custombuilt gas permeation unit. The SILMs were stable up to 0.6 MPa at room temperature without leaching the ionic liquid. [BSmim][tos] was recorded to have the highest solubility coefficient and permeability for CO2, among other ILs. At 0.5 MPa, for pure CO2/N-2 and CO2/CH4, IL [BSmim][tos] was observed with selectivities of 56.2 and 47.5, respectively. Based on the SILMs separation performance, the ILs synthesized for this work can be ranked as [BSmim][tos] > [BSmpy][tos] > [Bmim][Cl] > [Bpy][Cl]. Moreover, the exceptionally high selectivity values of [BSmim][tos] and [BSmpy][tos] confirms the potential use of ILs for CO2 separation through SILMs. (C) 2020 Elsevier Ltd. All rights reserved.

Hypoxia-induced biosynthesis of gold nanoparticles in the living brain

While a large number of studies deal with biomedical applications of various types of nanoparticles synthesized using wet chemistry, we propose the concept of targeted biosynthesis of nanoparticles in the living brain. Here we demonstrate that the pathological biochemical process of accumulation of reduced pyridine nucleotides under deleterious conditions of brain hypoxia can be redirected to drive the biosynthesis of biocompatible Au nanoparticles from a precursor salt in situ in the immediate vicinity of the hypoxia site, thereby restoring the redox status of the brain.

DNA topoisomerases as additional targets for anticancer monofunctional platinum(II) complexes

Topoisomerases are ubiquitous enzymes and important targets for DNA-oriented anticancer drugs. Two mitochondrion-targeted monofunctional platinum(II) complexes, [Pt(ortho-PPh3CH2Py)(NH3)(2)Cl](NO3)(2) (OPT) and [Pt(para-PPh3CH2Py)(NH3)(2)Cl](NO3)(2) (PPT; PPh3 = triphenylphosphonium, Py = pyridine), show significant inhibition towards the activity of DNA topoisomerases in addition to their DNA binding and mitochondrial targeting capabilities. OPT exhibits strong cytotoxicity toward the human renal clear cell carcinoma 786-O and the murine prostate cancer RM-1 cell lines. The complex could bind to the minor groove of DNA, as well as DNA topoisomerases I and II alpha, thereby acting as an inhibitor of topoisomerase I/II alpha and causing DNA damage. The damage was evidenced by the enhanced expression of gamma-H2AX, Chk1/2 phosphorylation, p53 and cell cycle arrest in the G2/M phase. In contrast, the inhibitory effect of PPT on DNA topoisomerases was largely limited to the isolated enzymes. The results demonstrate that the cellular inhibition of the complex towards the DNA topoisomerases positively correlated with its mitochondrial accumulation. Molecular docking provided more detailed structural insights into the interactions of OPT or PPT with DNA and topoisomerase I/II alpha. The binding sites of OPT and PPT in topoisomerase-DNA complexes are different from each other. Aside from previously revealed DNA and mitochondrial targets, this study discovered new evidence that DNA topoisomerases may also serve as targets of monofunctional platinum(ii) complexes. For a multispecific platinum complex, strong DNA binding ability does not necessarily lead to potent cytotoxicity as other factors including the cell types, mitochondrial accumulation, and activity of DNA topoisomerases also affect the outcome of DNA damage.

Conformer Specific Ultraviolet and Infrared Detection of Nicotine in the Vapor Phase

A gas-phase electronic spectrum of nicotine in a supersonic expansion has been recorded using two-color resonant two-photon ionization spectroscopy. Efficient photoionization was achievable only via the pyridine chromophore owing to poor Franck-Condon overlap in the N-methylpyrrolidine moiety. Two conformers of nicotine have been characterized and assigned by infrared-ultraviolet (IR-UV) ion depletion and IR-UV hole-burning spectroscopy, in combination with quantum chemical techniques. Trans-A with nitrogen atoms further apart is more stable by 2 kJ mol(-1) and the most populated conformer in the supersonic jet, owing this stability to a stronger inter-ring CH center dot center dot center dot N hydrogen bond than the trans-B counterpart.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1539-42-0 is helpful to your research. Product Details of 1539-42-0.
