We report on a new approach for creating water-soluble functionalized vesicles employing N-alkyl-3-boronopyridinium triflates (alkyl = Me, C12H25, C16H33) as sensors monosaccharides. The nanoaggregate properties were studied by means of DLS, TEM, high-resolution (1)H NMR, and the solvatochromic dyes Reichardt's betaine Methyl Orange. shown to have 30-200 nm diameters depending amphiphile chain length. Diol binding was steady-state fluorescence UV-vis using Alizarin Red S probe in solution at...
2,4,5,7-Tetranitro-9-fluorenone (1b) reacts readily with n-butanethiol in dipolar aprotic solvents selective substitution of nitro groups by butylsulfanyl positions 2 and 7 (2, 3); the 2,5-isomer 4 was formed only as a minor product (<1%). Condensation fluorenones 2-4 malononitrile yielded 9-dicyanomethylene derivatives 5-7, which showed strong intramolecular charge transfer (lambda approximately 510-560 nm) were found to sensitize photoconductivity carbazole-containing polymer films....
The synthesis and physical properties of four series novel fluorene push−pull compounds (4−7) the D−π−A type with intramolecular charge transfer (from 1,3- 1,2-dithiole 1,3-selenathiole donor (D) moieties) are described. nature heteroatom (S or Se) in fragment has no effect on maxima absorption bands (λICT), whereas a change position heteroatoms dithiole moiety from 1,3 to 1,2 leads substantial bathochromic shift λICT. Solvatochromism, thermochromism, negative halochromism these...
The synthesis and physical properties of a series novel fluorene π-electron acceptors (7−9) are described. Cyclic voltammograms 7 8 exhibit three separate reversible (or quasi-reversible) one-electron redox waves, characteristic strong electron acceptors. Spectroelectrochemical experiments show the appearance in long-wavelength visible region absorption bands at appropriate potentials which were attributed to transformations A → A•- A2-. Charge-transfer complexation with N-propylcarbazole...
A new sterically shielded carbene with branched aromatic substituents (9a) and two palladium halogenide complexes (11a,b) have been prepared. The single crystal X-ray structures of free 9a 10b 11a were determined. Very high catalytic efficiencies evident for the 11a,b when latter employed as catalysts hydrodechlorination chloroarenes p-dichlorobenzene hexachlorobenzene. When optimized, foregoing approach is significantly more effective than those currently known transition metal complexes....
Abstract Due to population upsurge, pesticides (derivatives of organophosphorus acids included) find widespread use in agriculture. The toxicity and long-term environmental hazard such compounds require detailed studies on decomposition mechanisms the development efficient, readily available, inexpensive systems for their decontamination. A simple straightforward method involves reactions with nucleophiles. Studies reactivity "normal" α-nucleophiles toward electron-deficient centers allowed...
The new sterically shielded 1,3,4-trisubstituted 1,2,4-triazol-5-ylidenes 8b–d were synthesized by a three step method starting from 2-phenyl-1,3,4-oxadiazole. syntheses of palladium complexes 9a–d and 10a–d (including the derivatives 9c,d 10a–d) carried out via reactions stable carbenes 8a–d with halogenide salts in THF or toluene solution. Complexes found to be excellent catalysts for reductive dechlorination (hydrodechlorination) p-dichlorobenzene. structures 8c, 9a,b, 10a determined...
Strong intramolecular charge transfer (ICT) in fluorenes 2 and 3 from a donor amino group to acceptor fluorene moiety leads exceptionally easy rotation around the C(9)(α) bond that has been registered by 1H NMR spectroscopy; single crystal X-ray analysis of 2i confirms changes numbers. Cyclic voltammetry (CV) compounds shows two closely spaced reversible single-electron reduction waves (in range –0.4 V –1.16 V, E1red½– E2red½⩽ 0.16 V) resulting radical anions dianions, respectively, third...
Hypobromite ion, BrO-, is an effective α-nucleophile that reacts rapidly with activated phosphorus(V) and sulfonate esters. The parent acid oxidizes organic sulfides aryloxide ions. At pH 10−11 BrO- HOBr coexist in water are potentially useful as decontaminants of chlorosulfide blister agents the phosphonyl nerve agents. Bis(dialkylamide)hydrogen dibromobromates well characterized, stable, solids which form HOBr−BrO- mildly alkaline water. Reactions 4-nitrophenyl diethyl phosphate...
Analysis of data for the transmission electronic effects in various biaryl systems has shown that introduction a bridge group between two benzene rings can both weaken and enhance interaction substituent functional centre located different rings.
