A nanocomposite was formed by adding fumed silica to the high-permeability random copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (PDD). The self-diffusion constant of pentane in cast films of the pure polymer and nanocomposites containing 10, 20, 25, and 30 wt % fumed silica was measured. The addition of 30 wt % fumed silica increased the self-diffusion constant by an order of magnitude. For the pure polymer and all four nanocomposite compositions, the apparent self-diffusion constants are a function of the time over which diffusion is observed, Delta, in the pulse field gradient experiment. At a given level of fumed silica, diffusion appears to be faster when observed over shorter times and decreases toward a plateau value at long times. This result is qualitatively indicative of tortuous diffusion. The addition of fumed silica not only increases the apparent self-diffusion constants but also changes the dependence of the apparent self-diffusion constants on Delta. The self-diffusion constants decrease more slowly as a function of Delta, indicating better connectivity of the more permeable domains. The apparent diffusion constants also increase as a function of time after the introduction of pentane. This phenomenon is observed in the pure polymer as well and is described as conditioning of the membrane. Conditioning of the membrane increases diffusion constants initially; but after a few months, aging of the membrane leads to a decrease in translational mobility.

Fluoropolymers are receiving considerable attention for use as integrated circuit dielectric materials. There is considerable confusion regarding the thermal stability of these materials. It is desirable to discuss thermal stability in terms of the outgassing properties of thin films deposited onto silicon wafers, since this is a key indicator of the fitness for use of a given dielectric film technology. In this paper we discuss the various types of fluoropolymer films and review previously published data on their thermal stability. Two such fluoropolymers, polytetrafluoroethylene (PTFE) and a copolymer of tetrafluoroethylene and 2,2-bistrifluoromethy-1-4,5-difluoro-1,3-dioxole (TFE-PDD), have been previously proposed for use as integrated circuit dielectrics. Thermal Desorption Spectroscopy results for thin films of these two polymers are presented. These results show that PTFE has much lower outgassing than does TFE-PDD.

Neglected diseases represent a major health problem. It is estimated that one third of the world population is infected with tuberculosis and additionally Leishmaniosis and Chagas disease affect approximately 30 million people. N-Acylhydrazone moiety is a repeated functional group present in several prototypes and drug candidates for these neglected diseases. On the other hand, furoxan system has been studied as pharmacophore for Leishmaniosis and Chagas diseases. Here we report on the design and preparation of forty hybrid furoxanyl N-acylhydrazones and on their activity on Mycobacterium tuberculosis, H37Rv and MDR strains, Trypanosoma cruzi, and Leishmania amazonensis. Among them, four derivatives displayed excellent to good selectivity indexes against the three different microorganisms. Hybrid compound N’-(4-phenyl-3-furoxanylmethylidene)isoniazide 9 showed the best antibacterial profile with MIC value 4.5 lesser than the value for the reference isoniazid against MDR strain. Furoxanyl N-acylhydrazone (E)-2-methyl-N’-(4-phenyl-3-furoxanylmethylidene)-4H-imidazo[1,2-a] pyridine-3-carbohydrazide 15 was ten-fold more potent against T cruzi Amastigotes than the standard drug nifurtimox. On the other hand, derivatives (E)-N’-(5-benzofuroxanylmethylidene)benzo[d][1,3] dioxole-5-carbohydrazide 25 and (E)-N’-(4-hydroxy-3-methoxyphenylmethylidene)-3-methylfuroxan-4-carbohydrazide 37 emerged as leads for the development of new leishmanicidal agents. The adequate stability, in simulated biological system and plasma, and the lack of mutagenicity of these derivatives allow us to propose them as candidates for further pre-clinical studies.

Permeation and sorption of various organic liquids (chlorinated hydrocarbons, lower alcohols, hydrocarbons, etc.) in amorphous copolymers of 2,2-bis-trifluoromethyl-4,5-difluoro-1,3-dioxole and tetrafluoroethylene (amorphous Teflons AF) were studied in the temperature range 5-95 degreesC. Based on permeation rate and solubility coefficients, the diffusion coefficients of organic penetrants in AF copolymers AF were estimated. It was shown that the copolymer with a higher content (87%) of the dioxole component (AF2400), as distinguished by a larger free volume, is much more permeable to liquids than the copolymer AF1600 containing 65% of the dioxole comonomer. In contrast, solubility of organic compounds in both copolymers is hardly affected by their composition. The effects of penetrant parameters, such as critical volume (V-c) and critical temperature (T-c) were analyzed. The variation in permeation rates of liquids and gases through these materials are consistent with a mobility (diffusion) controlled mechanism for mass transfer. A trade-off between the Arrhenius parameters for permeability and the van’t Hoff parameters for solubility is demonstrated for pervaporation. On this basis, novel correlations are obtained that enable a determination of the activation energy for permeation E-p and the enthalpy of sorption H-S from the permeability (P) and solubility (S) coefficients. Long term tests (up to 12 months) showed excellent time stability of the transport parameters, a property unexpected and quite important for a high flux, high free volume pervaporation material.

The reaction of Rh-II-oxocarbenoids derived from acyclic diazocarbonyl compounds with phthalimide and succinimide proceeds chemoselectively at the oxygen atom of the imidic carbonyl group, giving rise to the intermediate formation of carbonyl ylides. Intramolecular stabilization of these highly reactive species occurs in three different ways, and is controlled by the structure of the 2-oxocarbenoids. Carbonyl ylides from diazo esters mainly experience a [1,4]-hydrogen shift, and in this case, the corresponding O-alkylimidates are formed as the final products. These ylides may also be stabilized by 1,3-dipolar electrocyclization with intermediate formation of an oxirane. Carbonyl ylides with an acyl group in the carbene moiety undergo an intramolecular 1,5-dipolar electrocyclization to produce 1,3-dioxole derivatives. ((c) Wiley-VCH Verlag GmbH & Co.

Copolymers of perfluoro-2-ethyl-2-methyl-1,3-dioxole and perfluoro-5-methyl-3,6-dioxanon-1-ene were synthesized using high-pressure technique without initiators. Copolymers have molecular weight of (1.2-4) center dot 10(4) and possess high optical transparency in the telecommunication C-band region of 1530-1565 nm. Refractive index n of copolymers as a function of ether mol.% in the macromolecule x was investigated. It is established that the curve n(x) is non-monotonic, the difference of refractive indices of copolymers with various x differs by n = 0.015. The synthesized materials are amorphous, capable of film formation, and can be used for the fabrication of optical fibers and integrated optical waveguides with numerical aperture NA from 0.13 to 0.2, with waveguiding core and cladding made of perfluorinated materials.

An atomic force microscope has been employed to measure the force of interaction between a micron-sized colloidal sphere and a flat plate, both coated with a copolymer of perfluoro(2,2-dimethyl-1,3-dioxole) and tetrafluoroethylene (Teflon AF1600) in water, glycerol, formamide, ethylene glycol, ethylammonium nitrate, formic acid, ethanol, methanol, diiodomethane, 1-bromonaphthalene, hexadecane, and hexane. A long-range force of attraction was measured in water and, with the exception of the n-alkanols and n-alkanes, all the organic liquids. The results indicate that there is a macroscopic long-range attraction between solvophobic surfaces that has a different origin from that of the hydrophobic interaction observed at the molecular level, The results also indicate that there is a solvophobic force that is not due to either orientational ordering propagated by hydrogen bonds, electrostatic (or polarization) effects, or condensates of loosely attached surface material; all mechanisms that have been invoked previously to explain the macroscopic hydrophobic force. The force curves measured in the organic liquids provide a new perspective which is consistent with the hypothesis that submicroscopic air bubbles adhering to the macroscopic surfaces are responsible for a long-range attraction.

In the title compound, C11H12O2S2, two independent but virtually superimposable molecules, A and B, comprise the asymmetric unit. In each molecule, the 1,3-dithiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the plane through the remaining four atoms. The substituted benzene ring occupies an equatorial position in each case and forms dihedral angles of 85.62 (9) (molecule A) and 85.69 (8)degrees (molecule B) with the least-squares plane through the 1,3-dithiane ring. The difference between the molecules rests in the conformation of the five-membered 1,3-dioxole ring which is an envelope in molecule A (the methylene C atom is the flap) and almost planar in molecule B (r.m.s. deviation = 0.046 angstrom). In the crystal, molecules of A self-associate into supramolecular zigzag chains (generated by glide symmetry along the c axis) via methylene C-H center dot center dot center dot pi interactions. Molecules of B form similar chains. The chains pack with no specific directional intermolecular interactions between them.
