Gas permeation in thin films of high free-volume glassy perfluoropolymers: Part II. CO2 plasticization and sorption

Carbon dioxide (CO2) plasticization and sorption effects in both thick and thin films of high free-volume glassy perfluoropolymers were studied by monitoring CO2 permeability and by observing changes in the film thickness and refractive index with ellipsometry measurements. The film thickness, aging time, thermal history and CO2 exposure protocols have significant effect on the absolute CO2 permeability and plasticization behavior of both thick and thin films. The extent of CO2 plasticization increases as film thickness decreases and as the aging time is increased. The as-cast films showed higher plasticization compared to films which were annealed above T-g; however, the CO2 permeability of both the ascast and annealed films continuously decreased during the depressurization step unlike other glassy polymers. In general, the various CO2 exposure protocols revealed lower CO2 plasticization for perfluoropolymers compared to other reported glassy polymers. The extent of CO2 sorption obtained from the ellipsometry measurements was found to decrease with the decrease in the excess volume and increase in the aging time for perfluoropolymers; in addition, the structural differences among the various glassy polymers resulting in different polymer-gas interactions also affects the overall sorption characteristics. The lower plasticization in perfluoropolymers compared to Matrimid was also confirmed from the smaller percent increase observed for the experimental diffusion coefficient compared to the theoretically predicted diffusion coefficient from the dual sorption-mobility model. The Langmuir sorption parameter, C-H’, and solubility at infinite dilution, So, obtained from fitting dual sorption-mobility model to sorption data, showed an excellent linear correlation with (T-g-35) degrees C. The CO2 diffusivity and permeability data obtained for thin films of various glassy polymers also showed a strong correlation with free volume. The somewhat unusual behavior of thin films of AF 2400 in comparison to other glassy polymers studied to date is believed to be related to the low cohesive energy density expected of perfluorinated structures and its high free volume resulting from the bulky dioxole comonomer.

Ab initio determination of geometries and vibrational characteristics of building blocks of organic super-conductors: TTF and its derivatives

Molecular behavior of the building block ([2-(1,3-dithiole-2-ylidene)-1,3-dithiole] =tetrathiafulvalene (TTF)} of organic superconductors have been investigated along with its three derivatives, namely, {[2-(1,3-dioxole-2-ylidene)-1,3-dioxole] tetraoxafulvalene (TOF)}; [2,2]-bi-[[1,3] oxathiolylidene]=Der I and 2-(3H-Furan-2-ylidene)-[1,3] oxathiole=Der II. The properties of the molecules such as molecular geometries, frontier MOs and vibrational spectra have been investigated by using DFT method at the B3LYP level employing 6-311++G(d,p) basis set. The geometrical parameters and atomic charges on various atomic sites of the TTF, TOF, Ders land II suggest extended conjugation in these systems. The present calculations lead to the reassignments for of some of the fundamentals and new interpretations for some of the observed IR and Raman frequencies. One of the two modes involved in the Fermi resonance giving rise to the doublet 1555 and 1564 cm(-1) needed to be revised and another doublet 3083 and 3108 cm(-1) could be interpreted as a Fermi resonance doublet. Out of the two nu(C=C) modes under the a(1) species, the lower frequency mode is assigned to the nu(C=C) of the ring and the higher one to the nu(C=C) of the central C=C bond contrary to the assignment reported in literature. The conducting properties of these molecules depend mainly on this mode. (C) 2012 Elsevier B.V. All rights reserved.

Amorphous Teflons AF as organophilic pervaporation materials Separation of mixtures of chloromethanes

Pervaporation of binary mixtures (CH2Cl2-CHCl3, CHCl3-CCl4 CH2Cl2-CCl4) through two amorphous copolymers of 2,2-bis-trifluoromethyl-4,5-difluoro-1,3-dioxole and tetrafluoroethylene was studied at different temperatures, feed composition, and downstream pressure. It was shown that the copolymer with the larger content of the dioxole comonomer and having the greater free volume (AF 2400) is more permeable, whereas selectivity of separation of the two copolymers are similar for some regimes. The dependence of permeation rate and selectivity on the process parameters of the AF copolymers indicated that mobility selectivity prevails for pervaporation of the mixtures studied through these membrane materials. The deviation coefficients used for analysis of mixed permeation indicated strong interactions of the components in pervaporation of binary mixtures. Pervaporation separation index (PSI), which depends on permeability and selectivity of pervaporation, was used to characterize the performance of the process. It was shown that PSI increases for higher contents of the components enriched in the permeate and at higher temperatures. (C) 2004 Elsevier B.V. All rights reserved.

Solvent dependence of rotational anisotropy and molecular geometry as probed by NMR cross-relaxation rates

A medium size and rigid molecule (2,3-naphto-1,3-dioxole) has been selected for this study because full anisotropic reorientation is expected and because its symmetry elements dictate the orientation of the rotation-diffusion tensor. NMR measurements include direct cross-relaxation rates (which yield the three rotation-diffusion coefficients by assuming the length of CH bonds) and remote cross-relaxation rates (which, by using these rotation-diffusion coefficients, yield distances between a given carbon and remote protons). Two different solvents have been used: carbon disulfide and dimethyl sulfoxide, In both solvents, the same type of reorientation anisotropy is observed although with different ratios of rotation-diffusion coefficient values, presumably due to specific intermolecular interactions undergone by the dioxole ring. This would also explain geometrical variations at the level of this moiety. (C) 2002 Published by Elsevier Science B.V.

THE CHEMOENZYMATIC reaction of selected aldehydes, namely 2-chlorobenzaldehyde (1a), 4-fluorobenzaldehyde (1b), benzo[d][1,3] dioxole-5-carbaldehyde (1c) and/or 2,3-dihydrobenzo [b] [1,4]dioxine-6-carbaldehyde (1d) with hydrogen cyanide in presence of (R)-oxynitrilase (R)-Pa HNL [EC 4.1.2.10] from almonds, as a chiral catalyst, gave the optically active cyanohydrin enantiomers (R)2a-c, respectively. Acetone cyanohydrin (3), was also used, as a transcyanating agent, to give the same products. The racemic cyanohydrins (R, S)-2a-d have been synthesized, as well, by treating compounds 1a-d with aqueous potassium cyanide solution in presence of a saturated solution of sodium metabisulphite (Na2S2O5). The optical purity of cyanohydrins (R)-2a-c was determined through their derivatization with (S)-naproxen chloride (S)-5 to the respective diastereomers (R, 2S)-6a-c which were obtained in diastereomeric excess (de) values up to 93 % (H-1 NMR). Heating compounds (R)-2a, b and / or their racemic analogues (R, S)-2a-c with concentrated hydrochloric acid gave the respective alpha-hydroxycarboxylic acids 7a-c. Moreover, reduction of cyanohydrins (R, S)-2b,c under different conditions resulted in a hydrodecyanation giving the respective primary alcohols 8a, b. Structures and configurations of the new compounds were confirmed with compatible elementary microanalyses and spectroscopic (IR, H-1 NMR, C-13 NMR, MS and single crystal X-ray crystallography) measurements. The antimicrobial activity of derivatives 6a-d against four bacterial species (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and two fungi (Aspergillus flavus and Candida albicans) were undertaken. Moreover, compounds (R,2S)-6b, (R, 2S)(S, 2S)-6b and (R, 2S)-6c were screened for their in virto antitumor activity against three human solid cancer cell lines (HCT 116, HepG2 and MCF-7). In general, the tested compounds were found inactive or showed weak activities in comparison with the standard drugs.

Fluoropolymer-Stabilized Chromophore-Catalyst Assemblies in Aqueous Buffer Solutions for Water-Oxidation Catalysis

In the procedure, the polymer was dip-coated onto the surfaces of oxide electrodes with pre-bound, phosphonate-derivatized chromophores and assemblies, including assemblies for water oxidation. The results of the experiments showed a high degree of stabilization by the added polymer and a demonstration of its use in stabilizing surface-bound assemblies for water-oxidation catalysis.
