Peroxidic perfluoropolyethers (PFPEs) are industrial intermediates used by Solvay Solexis for the preparation of different classes of (per)fluoropolyethers (Fomblin (R), Galden (R), Solvera (R), Fluorolink (R)). The chemistry of these peroxidic compounds has been recently exploited for the synthesis of novel PFPE block copolymers. In the present work we report the synthesis, the structural and physical-chemical characterization of block copolymers obtained by the reaction of peroxidic PFPEs with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole, a cyclic homopolymerizable perfluoroolefin. These block copolymers combine the most attractive properties of the PFPEs, like the excellent lubrication, the high thermal stability and the optical transparency, with new specific properties which are related to the perfluorodioxolenic blocks.

Difluorinated alkenoate ethyl 3,3-difluoro-2-(N, N-diethylcarbamoyloxy)-2-propenoate reacts rapidly and in high yield with furan and a range of substituted furans in the presence of a tin(IV) catalyst. Non-fluorinated congener 2-(N, N-diethylcarbamoyloxy)-2-propenoate fails to react at all under the same conditions. These reactions have been explored using density functional theory (DFT) calculations. They reveal a highly polar transition state, which is stabilized by the Lewis acid catalyst SnCl4 and by polar solvents. In the presence of both catalyst and solvent, a two-step reaction is predicted, corresponding to the stepwise formation of the two new carbon-carbon bonds via transition states which have similar energies in all cases. Our experimental observations of the lack of reaction of the non-fluorinated dienophile, the stereochemical outcomes, and the rate acceleration accompanying furan methylation are all well predicted by our calculations. The calculated free energy barriers generally correlate well with measured reaction rates, supporting a reaction mechanism in which zwitterionic character is developed strongly. An in situ ring opening reaction of exo-cycloadduct ethyl exo-2-(N, N-diethylcarbamoyloxy)-3,3-difluoro-7-oxabicyclo[2.2.1] hept-5-enyl-2-endo-carboxylate, which results in the formation of cyclic carbonate ethyl 4,4-difluoro-5-hydroxy-2-oxo-5,7a-dihydro-4H-benzo[1,3] dioxole-3a-carboxylate by a Curtin-Hammett mechanism, has also been examined. Substantial steric opposition to Lewis acid binding prevents carbonate formation from 2-substituted furans.

Solvent swelling of polymers is of major importance in organic solvent nanofiltration (OSN) affecting membrane rejection of 200-1000 + Da solutes. A selected perfluoro type amorphous glassy copolymer, perfluoro-2,2-dimethyl-1,3-dioxole copolymerized with tetrafluoroethylene (PDD-TFE), is completely insoluble in all solvents except perflourinated solvents; further it showed very little swelling in solvents that are not of the perfluorinated type. Pure component permeation flux for a particular variety of this copolymer, CMS-7, was measured with a wide variety of solvents for two membrane thicknesses, 1.67 in and 0.6 pm, in a composite form supported on a porous ePTFE substrate. The feed pressure range was 1000-3000 kPa. The solvents included methanol, ethanol, ethyl acetate, n-heptane, tetrahydrofuran (THF), toluene, dimethylsulfoxide (DMSO); n-heptane showed much higher flux than the rest. Successful OSN was demonstrated with high solute rejection in methanol solutions of two dye solutes Safranin 0 (MW, 351 Da) and Brilliant Blue R (MW, 826 Da). Rejection for Safranin 0 varied between 94% and 97% depending on the pressure and membrane thickness; that for Brilliant Blue R varied in the range of 97-99.8%. Successful OSN was also demonstrated with Safranin 0 in THF with solute rejection varying between 94% and 97%. Permeation behaviors of various mixtures of two solvents, toluene and n-heptane, were studied. The measured values of very limited extent of sorption of a variety of organic solvents in 25 pm thick dense samples of this and a related perfluoro type copolymer, CMS-3, were employed to explain the observed behavior.

Mixed matrix membranes of synthesized polyurethane (PU) based on toluene diisocyanate (TDI), polydimethylsiloxane (PDMS) and polytetramethylene glycol (PTMG) with polyvinyl alcohol based polar silica particles were prepared by solution casting technique. The homogeneity and thermal properties of the prepared PDMS-PU/silica membranes were characterized using scanning electron microscope (SEM), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). The SEM micrographs confirmed the distribution of silica particles in the polymer matrix without agglomerations. Gas permeation properties of membranes with different silica contents were studied for pure CO2, CH4, O-2, He and N-2 gases. The obtained results indicated the permeability of the condensable and polar CO2 gas was enhanced whereas permeability of other gases decreased upon increasing the silica content of the mixed matrix membranes. The permeability of CO2 and its selectivity over N-2 was increased from 68.4 Barrer and 22 in pure PDMS-PU to 96.7 Barrer and 64.4 in the mixed matrix membranes containing 10 wt% of the silica particles.

In connection with a total synthesis of cephalotaxine (1a), we have examined the addition of various nucleophilic reagents to [ABC] subunits 2 and 7 possessing a pyrrolobenzazepine core. In fact, this reaction implicates invariably the carbonyl group of 2. Regarding the reaction of 7 with nucleophiles, the most striking aspect is the complete lack of reactivity of the enaminonitrile moiety. For instance, the condensation of 7 with methylmagnesium bromide involves exclusively the cleavage of the dioxole ring, yielding regioisomers 9 and 10. With the aim of understanding the unexpected reactivity of 2 and 7 toward nucleophiles, crystallographic studies of 2 and 7 and an experimental electron density determination of 7 were carried out. The marked reactivity of the carbonyl group of 2 was interpreted by invoking the weakness of the amide resonance, due to a pronounced delocalization of the N-9 lone pair over the enaminonitrile moiety. The electron density study of 7 reveals this electron delocalization along the enaminonitrile fragment, highlighted and quantified through the bond geometries, topological indicators, and atomic charges, a phenomenon that is responsible for the failure of the addition of nucleophilic species.

Fluorous Polymeric Membranes for Ionophore-Based Ion-Selective Potentiometry: How Inert Is Teflon AF?

Fluorous media are the least polar and polarizable condensed phases known. Their use as membrane materials considerably increases the selectivity and robustness of ion-selective electrodes (ISEs). In this research, a fluorous amorphous perfluoropolymer was used for the first time as a matrix for an ISE membrane. Electrodes for pH measurements with membranes composed of poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole]-co-poly(tetrafluoroethylene) (87% dioxole monomer content; known as Teflon AF2400) as polymer matrix, a linear perfluorooligoether as plasticizer, sodium tetrakis[3,5-bis(perfluorohexyl)phenyl]borate providing for ionic sites, and bis[(perfluorooctyl)propyl]-2,2,2-trifluoroethylamine as H+ ionophore were investigated. All electrodes had excellent potentiometric selectivities, showed Nernstian responses to H+ over a wide pH range, exhibited enhanced mechanical stability, and maintained their selectivity over at least 4 weeks. For membranes of low ionophore concentration, the polymer affected the sensor selectivity noticeably at polymer concentrations exceeding 15%. Also, the membrane resistance increased quite strongly at high polymer concentrations, which cannot be explained by the Mackie-Meares obstruction model. The selectivities and resistances depend on the polymer concentration because of a functional group associated with Teflon AF2400, with a concentration of one functional group per 854 monomer units of the polymer. In the fluorous environment of these membranes, this functional group binds to Na+, K+, Ca2+, and the unprotonated ionophore with binding constants of 10(3.5), 10(1.8), 10(6.8), and 10(4.4) M-1, respectively. Potentiometric and spectroscopic evidence indicates that these functional groups are COCH groups formed by the hydrolysis of carboxylic acid fluoride (COF) groups originally present in Teflon AF2400. The use of higher ionophore concentrations removes the undesirable effect of these COOH groups almost completely. Alternatively, the C(=O)F groups can be eliminated chemically, or they can be used to readily introduce new functionalities.

Study on the Electrical Conductive Mechanism in the Five-layered Structure of Organic Light-emitting Diodes

The Electrical conductive mechanism was studied using a five-layered structure of organic light-emitting diodes. The manufactured device structure was ITO/2,2-bistrifluoromethyl-4,5-difluoro-1,3-dioxole (AF)/N,N’-diphenyl-N,N’bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine(TPD)/tris(8-hydroxyquinoline)aluminum (Alq(3))/(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP)/LiF/Al. From the analysis of the current density-luminance-voltage characteristics of the five-layered device, four conductive mechanisms depending on the applied voltage region were found. In the Schottky region, where the electric field E is below 1.6 x 10(5) V/cm, the obtained Schottky coefficient beta(ST) is 3.98 x 10(-24) JV(-1/2)m(1/2). In the negative-resistance region, where the electric field is below 3.7 x 10(5) V/cm, the current density J is proportional to E(-2.41), In the Poole-Frenkel region, where the electric field is below 6.4 x 10(5) V/cm, the obtained Poole-Frenkel coefficient beta(P F) is 7.80 x 10(-24) JV(-1/2)m(1/2). The experiment obtained value of beta(P F) corresponds to 1.96 times that of beta(ST), which is theoretically expected because beta(P F) = 2 beta(ST). In the Folwer-Nordheim region, where the electric field is above 8.30 x 10(5) V/cm, the obtained potential barrier empty set(F N) is 0.42 eV.

Experimental and Computational Evaluation of Piperonylic Acid Derived Hydrazones Bearing Isatin Moieties as Dual Inhibitors of Cholinesterases and Monoamine Oxidases

A set of piperonylic acid derived hydrazones with variable isatin moieties was synthesized and evaluated for their inhibitory activity against the enzymes acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and monoamine oxidases A and B (MAO-A/B). The results of in vitro studies revealed IC50 values in the micromolar range, with the majority of the compounds showing selectivity for the MAO-B isoform. N-[2-Oxo-1-(prop-2-ynyl)indolin-3-ylidene]benzo[d][1,3]dioxole-5-carbohydrazide (3) was identified as a lead AChE inhibitor with IC50=0.052 +/- 0.006 mu m. N-[(3E)-5-chloro-2-oxo-2,3-dihydro-1H-indol-3-ylidene]-2H-1,3-benzodioxole-5-carbohydrazide (2) was the lead MAO-B inhibitor with IC50=0.034 +/- 0.007 mu m, and showed 50 times greater selectivity for MAO-B over MAO-A. The kinetic studies revealed that compounds 2 and 3 displayed competitive and reversible inhibition of AChE and MAO-B, respectively. The molecular docking studies revealed the significance of hydrophobic interactions in the active site pocket of the enzymes under investigation. Further optimization studies might lead to the development of potential neurotherapeutic agents.

Block copolymer compatibilized polymer: fullerene blend morphology and properties

Recent studies have shown the role of block copolymer as compatibilizer in tuning the phase separated morphology of the active layer so as to improve the overall photovoltaic efficiency of organic photovoltaic (OPV) devices. Here, we substantiate this observation by investigating the role of a rod-coil block copolymer poly-(3-hexylthiophene)-b-polystyrene (P3HT-b-PS) as compatibilizer in influencing the blend morphology and device performance of several polymer:fullerene blend systems. Fullerene derivatives N-(3-methoxypropyl)-2-(carboxyethyl)-5-(4-cyanophenyl) fulleropyrrolidine (NCPF) and N-(3-methoxypropyl)-2-(carboxyethyl)-5-(5, 5-difluorobenzo-dioxole) fulleropyrrolidine (FFNCPF) were synthesized using Prato reaction, while P3HT-b-PS copolymer was synthesized using the combination of Grignard metathesis, ATRP, and click chemistry. The addition of P3HT-b-PS in P3HT:PCBM blend led to the formation of more homogenous structure compared to the pure P3HT:PCBM blend. Also, a reduction in domain size was observed in P3HT: FFNCPF system upon P3HT-b-PS addition which can be attributed to the compatibilization effect of BCP. Incorporation of P3HT-b-PS block copolymer was found to effectively alter the thin film nanostructure of polymer/fullerene derivative blends and polymer crystalline structure. Maximum enhancement in power conversion efficiency (PCE) of compatabilized P3HT:PCBM blend system was noticed followed by P3HT:FFNCPF and P3HT:NCPF. The moderate improvement in photovoltaic properties can be correlated with face-on orientation of P3HT crystallites and the segregation of the fullerene domains at the bulk heterojunction (BHJ) cathode interface which facilitates the efficient charge collection as respective electrodes.
