A series of azobenzene containing copolymers were synthesized by post-modification of poly(methyl methacrylate-co-pentafluorophenyl methacrylate) with an amine-functionalized azobenzene. Light- and thermo-responsive behavior of these copolymers was investigated in ethanol–water solvent mixtures...

Poly(2-hydroxyethyl methacrylate)-based materials bearing porphyrinic units were prepared, characterized and their ability to inactivate Escherichia coli and Staphylococcus aureus bacteria was evaluated. Porphyrins containing methacrylate moieties were prepared by the sequential nucleophilic sub...

N-pentafluorophenyl maleimide (PFPMI) was synthesized. The homo and copolymers of PFPMI with methyl methacrylate (MMA) were prepared. The monomer reactivity ratio, r1 (PFPMI) and r2 (MMA) were 0.389 and 1.06 respectively. Q and e values for PFPMI were calculated as 1.00 and 1.30. The refractive ...

Poly[1,1,1,3,3,3-hexafluoro-2-(pentafluorophenyl)propan-2-yl methacrylate (I)] was synthesized, and the copolymers of the monomer I with various compositions of methyl methacrylate (MMA) were prepared and characterized. The glass transition temperature values obtained for the copolymers were bet...

Poly(pentafluorophenyl methacrylate) (PPFPMA) was first subjected to post-polymerization modification with oligo(ethylene glycol) methyl ether amine (OEG-NH2) and yielded poly(pentafluorophenyl methacrylate)-co-poly(oligo(ethylene glycol methacrylamide)), PPFPMA-co-POEGMAM. These amphiphilic ran...

As a novel base material for low-loss graded index plastic optical fibers (GI POFs) in gigabit home networks, a copolymer of methyl methacrylate (MMA) and pentafluorophenyl methacrylate (PFPMA) was prepared and its thermal and optical properties were investigated. When the PFPMA content in the m...

The seven poly(methyl methacrylate-co-pentafluorophenyl methacrylate) [P(MMA-co-PnFPMA)] copolymers were prepared by dispersion polymerization under supercritical carbon dioxide. The physicochemical characterisation for the P(MMA-co-PnFPMA) was investigated with varied mole ratios of MMA vs PnFP...

One of the most important factors for the proper functioning of enzymatic electrochemical biosensors is the enzyme immobilization strategy. In this work, glucose oxidase was covalently immobilized using pentafluorophenyl methacrylate (PFM) by applying two different surface modification technique...

An experimental model resembling the “locked-lung syndrome” in humans has been produced in dogs, and the efficacy of soterenol, a new bronchodilator agent, has been studied. In a group of dogs in which isoproterenol was either ineffective or caused bronchoconstriction, soterenol, administered ...

The oxidation of soterenol and subsequent reaction of the substituted o-quinoneimine in acidic media were studied by cyclic voltammetry, flow-through coulometry, liquid chromatography combined with electrochemistry and fluorescence spectroscopy. The methanesulfonamide group is readily hydrolyzed...

Treatment with soterenol (0.3–300 μg/kg, i.v.) increased the mean arterial blood pressure and decreased heart rate in rabbits. Soterenol caused a dose-dependent contraction of rabbit aorta and portal vein, guinea-pig vas deferens and cat nictitating membrane which was inhibited by phentolamine...

Methanesulfonanilides, like soterenol and mesuprine, which are bioisosteric with adrenergic catecholamines, form fluorescent species when subjected to the trihydroxyindole reaction. Presumably, the fluorescence is due to adrenolutin‐like species formed from aminochrome intermediates. Fluorescen...

Direct C-lithiation of β-functionally-substituted acrylates yields versatile building units for syntheses of butenolides, tetronates, cyclopentenones and derivatives, which are portions of many natural products. A wide variety of α- and β-substituents are compatible with this lithiation: alky...

An attractive method for assembling π-conjugated dienynes with high stereoselectivity was achieved by dehydration reaction of TMS-substituted [3]cumulenols catalyzed by TsOH·H2O. On the other hand, cycloisomerizations of the corresponding [3]cumulenones catalyzed by gold(I) complexes afford vi...

The conformational equilibria in solutions of the title compound were studied by a combined kinetic and statistical fluorimetric analysis in 9:1 methylcyclohexane/3-methylpentane at 293 K. The temperature and solvent effects on the equilibrium were also investigated. Two rotamers were evidenced:...

An intuitive approach to differentially all-carbon tetrasubstituted olefins from a scaffold of (E)-1-bromo-2-iodoalkenes is described. The iodine atom of the scaffold selectively undertook CuTC-mediated cross-coupling reactions with organotin reagents, suppressing a side-reaction of β-halogen e...

The 73Ge NMR spectra of 2-thienyl, 2-furyl- and 2-(4,5-dihydrofuryl)germanes have been studied. The comparison of 73Ge chemical shifts with those of 29Si and 119Sn in isostructural silicon and tin derivatives confirms the existence of additional effects in these compounds. The contribution of th...

The palladium-catalyzed oxidative coupling of thiophenes and furans with alkenes proceeds in the presence of copper and lithium salts as oxidant and additive, respectively, under weakly basic or almost neutral conditions to afford the corresponding vinylated heteroarenes. Under such conditions, ...

Almond and VolSurf + modelling procedures allowed the structural design of new di- and mono-heteroaryl-ethylenes. The structural modifications suggested by the molecular modelling were verified by the synthesis of the designed molecules and by the evaluation of their in vitro activities against ...

The photosensitized oxidation of trans-2-styrylthiophenes (trans-2-ST), trans-3-styrylthiophenes (trans-3-ST) and trans-1,2-di(2-thienyl)ethylene (trans-2-TE) were investigated using the sensitizers tetraphenylporphyrin (TPP) in a non-polar solvent and 9,10-dicyanoanthracene (DCA) in a polar sol...
