One of the major stumbling blocks that has plagued the practical utilization and fundamental studies of the high-T_c superconductors has been the poor interfacial properties exhibited by these systems. In order to control the surface characteristics of high-T_c structures, methods for the spontaneous adsorption of amine reagents into cuprate materials have been developed. These monolayer films allow for control of the wetting properties, corrosion resistance, and adhesion characteristics of these superconductors. The mols. form densely packed, highly oriented structures on the high-T_c surfaces as evidenced by contact angle, XPS, x-ray reflectivity, and corrosion resistance measurements. In this paper, dramatic changes in the interfacial reactivity and adhesion properties of the prototypical high-T_c superconductor, YBa₂Cu₃O₇ , following its modification with linear alkylamines and fluorinated alkylamines reagents are described. Thus, mol. level control over important surface and interfacial properties of cuprate superconductors is demonstrated.

Hashidzume, Akihito published the artcileNMR and fluorescence studies of the self-association behavior of an amphiphilic polyanion bearing hydrocarbon and fluorocarbon hydrophobes, Product Details of C10H6F17N, the publication is Polymer (2011), 52(7), 1546-1553, database is CAplus.

The association behavior of the terpolymers of sodium 2-acrylamido-2-methylpropanesulfonate (NaAMPS), N-dodecylmethacrylamide (DodMAm), and N-(2-(perfluorooctyl)ethyl)methacrylamide (PFOEMAm) (A/H(x)/F(y)) and their reference copolymers of NaAMPS and PFOEMAm (A/F(y)) was characterized using ¹⁹F and ¹H NMR, steady state fluorescence, and dynamic light scattering techniques in water (or D₂O) containing 0.1 M NaCl. The terpolymers formed micelle-like aggregates where hydrophobic microdomains are formed by hydrophobic associations among the perfluorooctylethyl (PFOE) and dodecyl (Dod) groups, the PFOE group exhibiting a stronger tendency for interpolymer association than the Dod groups. A careful anal. of the characterization data led to a conclusion that the hydrophobic microdomain formed from the terpolymer is microscopically phase separated into the fluorocarbon phase and hydrocarbon phase.

The parallel synthesis of O-aryloxyamines remains an unfulfilled need in the field of medicinal chem. and fragment-based approaches. To fill this gap a solution-phase two-step process based on (1) a copper-catalyzed cross-coupling of aryl boronic acids with a fluorous tagged N-hydroxyphthalimide, and (2) a supported aminolysis was designed and optimized using Taguchi’s method. A library of O-aryloxyamines was synthesized in high yields with high purity and diversity.

Yagodkin, Andrey published the artcileStraightforward carbamoylation of nucleophilic compounds employing organic azides, phosphines, and aqueous trialkylammonium hydrogen carbonate, Related Products of catalysis-chemistry, the publication is Tetrahedron (2010), 66(12), 2210-2221, database is CAplus.

In the presence of aqueous trialkylammonium hydrogen carbonate, the Staudinger reaction leads to the intermediate formation of the corresponding isocyanate, which, in turn, reacts further with a nucleophilic reagent also present in the mixture and results in carbamoylation with good yield. On the basis of this reaction a practical carbamoylation procedure was devised and a comparative study on suitability of different solvents and phosphorus (III) derivatives for carbamoylation reaction was conducted. The versatility of the method was demonstrated by examples with different classes of nucleophilic compounds that included the aminomethyl resin and natural compounds that display poor solubility in organic solvents.

Jung, Byung Jun published the artcileAir-Operable, High-Mobility Organic Transistors with Semifluorinated Side Chains and Unsubstituted Naphthalenetetracarboxylic Diimide Cores: high Mobility and Environmental and Bias Stress Stability from the Perfluorooctylpropyl Side Chain, Name: 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecan-1-amine, the publication is Advanced Functional Materials (2010), 20(17), 2930-2944, database is CAplus.

N,N’-bis(3-(perfluoroctyl)propyl)-1,4,5,8-naphthalenetetracarboxylic acid diimide (8-3-NTCDI) was newly synthesized, as were related fluorooctylalkyl-NTCDIs and alkyl-NTCDIs. The 8-3-NTCDI-based organic thin-film transistor (OTFT) on an octadecyltrimethoxysilane (OTS)-treated Si/SiO₂ substrate shows apparent electron mobility approaching 0.7 cm² V^-1s^-1 in air. The fluorooctylethyl-NTCDI (8-2-NTCDI) and fluorooctylbutyl-NTCDI (8-4-NTCDI) had significantly inferior properties even though their chem. structures are only slightly different, and nonfluorinated decyl and undecyl NTCDIs did not operate predictably in air. From at. force microscopy, the 8-3-NTCDI active layer deposited with the substrate at 120¡ã forms a polycrystalline film with grain sizes >4¦Ìm. Mobilities were stable in air for one week. After 100 days in air, the average mobility of three OTFTs decreased from 0.62 to 0.12 cm² V^-1s^-1, but stabilized thereafter. The threshold voltage (V_T) increased by 15 V in air, but only by 3 V under nitrogen, after one week. On/off ratios were stable in air throughout. The authors also studied transistor stability to gate bias stress. The transistor on hexamethlydisilazane (HMDS) is more stable than that on OTS with mobility comparable to amorphous Si TFTs. V_T shifts caused by ON (30 V) and OFF (-20 V) gate bias stress for the HMDS samples for 1 h were 1.79 V and 1.27 V under N₂, resp., and relaxation times of 10⁶ and 10⁷ s were obtained using the stretched exponential model. These performances are promising for use in transparent display backplanes.

Studies of neutral biomols. in the gas phase allow for the study of mol. properties in the absence of solvent and charge effects, thus complementing spectroscopic and anal. methods in solution or in ion traps. Some properties, such as the static electronic susceptibility, are best accessed in experiments that act on the motion of the neutral mols. in an elec. field. Here, the authors screen seven peptides for their thermal stability and electron impact ionizability. The authors identify two tripeptides as sufficiently volatile and thermostable to be evaporated and interfered in the long-baseline universal matter-wave interferometer. Monitoring the deflection of the interferometric mol. nanopattern in a tailored external elec. field allows the authors to measure the static mol. susceptibility of Ala-Trp-Ala and Ala-Ala-Trp bearing fluorinated alkyl chains at C- and N-termini. The resp. values are 4¦Ð¦Å0 ¡Á 330 ¡À 150 ?3 and 4¦Ð¦Å0 ¡Á 270 ¡À 80 ?3.

Petit, F. published the artcileAssociating Polyelectrolytes with Perfluoroalkyl Side Chains: Aggregation in Aqueous Solution, Association with Surfactants, and Comparison with Hydrogenated Analogs, Application In Synthesis of 30670-30-5, the publication is Langmuir (1997), 13(16), 4229-4233, database is CAplus.

Derivatives of poly(sodium acrylate) bearing a few mole percent of perfluoroalkyl side chains were synthesized. Their solution properties were investigated by rheol. and compared to those of their hydrogenated analogs. As the hydrogenated modified polymers, these new materials display an associating behavior. In semidilute solution the modified polymer exhibits viscosities of several orders of magnitude higher than the unmodified poly(sodium acrylate). However, this viscosifying effect is more pronounced for the perfluorinated derivatives By comparing the rheol. behaviors we find that a polymer bearing C₇F₁₅CH₂ side groups is as associative as a polymer containing the same fraction of C₁₃H₂₇ chains. This is in agreement with Ravey and Stebe’s¹ conclusions concerning surfactant association that a CF₂ is equivalent to 1.7CH₂ as regards its hydrophobicity. Mixtures of the perfluorinated polymers with their hydrogenated analogs or with hydrogenated surfactants were successively studied. For low modification ratios (¡Ü7 mol %) and at concentration ranges close to the critical aggregation concentration the mixing is not ideal. This is in line with the nonideal behavior displayed by mixtures of perfluorinated and hydrogenated surfactants.

Glinel, K. published the artcileComparison of the associating behavior between neutral and anionic alkylperfluorinated pullulan derivatives, Application In Synthesis of 30670-30-5, the publication is Polymer (1999), 40(25), 7071-7081, database is CAplus.

New hydrophobically modified pullulans were synthesized in two ways: (i) neutral derivatives (HMPFs) obtained by direct esterification of pullulan with a perfluoroalkyl carboxylic acid (C₈F₁₇CH₂CH₂COOH), and (ii) ionic derivatives (HMCMPs) obtained by amidation of carboxymethylpullulan with two perfluoroalkylamines (C₇F₁₅CH₂NH₂ and C₈F₁₇CH₂CH₂NH₂). The molar hydrophobe contents ranged from 1.1 to 4.8% with respect to the anhydroglucose units. Associative properties in aqueous solutions were studied by rheol. and size-exclusion chromatog./light-scattering measurements. In dilute solution, the polymers form intermol. aggregates with a more compact conformation than that of precursors. In semi-dilute solution, the ionic derivatives are more viscosifying than neutral because of their better solubility This effect is significant as the alkylperfluorinated chain length increases.

Benzyl alcs. I [X = OMe, H, CO₂Na, CO₂Me, CO₂H] are oxidized cleanly and efficiently to the corresponding aldehydes II under irradiation using flavin photocatalysts, e.g., III [R¹ = R² = (CH₂)₂(CF₂)₇CF₃; R¹ = CH₂CH₂OMe, R² = Me, (CH₂)₂(CF₂)₇CF₃] and IV [R³ = H, Me, R⁴ = Ac; R³ = Me, R⁴ = C(:O)(CH₂)₁₄Me] and aerial oxygen as the terminal oxidant in homogeneous aqueous solution Turnover frequencies (TOF) of more than 800 h^-1 and turnover numbers (TON) of up to 68 were obtained. Several flavin photocatalysts with fluorinated or hydrophobic aliphatic chains were immobilized on solid supports like fluorous silica gel, reversed phase silica gel or entrapped in polyethylene pellets. The catalytic efficiency of the heterogeneous photocatalysts was studied for the oxidation of different benzyl alcs. in water and compared to the analogous homogeneous reactions. Removal of the heterogeneous photocatalyst stops the reaction conversion immediately, which shows that the immobilized flavin is the catalytically active species. The immobilized catalysts are stable, retain their reactivity if compared to the corresponding homogeneous systems and are easily removed from the reaction mixture and reused. TOF of up to 26 h^-1, TON of 280 and up to 3 reaction cycles without loss of activity are possible with the heterogeneous flavin photocatalysts.

The synthesis of different types of amphiphilic compounds containing peptidoamine groups leads to surfactants with original properties such as the ability to coordinate metal ions. Water soluble acylcarcinine and alkylamidocarnosine surfactants are compared and the preparation of a silyloxyalkylamidocarnosine is described. The latter can be copolymerized with tetraalkoxysilanes to yield amphipathic organo-mineral solids that are also good ligands for metal cations.
