To design versatile ordered nanomorphologies from the alternating sequence-controlled amphiphilic copolymers, in current work, we have investigated self-assembly behavior of a series prepared through reversible addition–fragmentation chain transfer (RAFT) polymerization methoxy poly(ethylene glycol) (mPEG) functionalized styrene (VBP) and fatty acid attached maleimide (MF) monomers. The copolymers efficiently induced self-aggregation pendant side chains to afford both micelle vesicle...
Abstract To develop glutamic acid derived cross‐linked polymeric organogels for dye adsorption from aqueous media, dimethyl 2‐(methacrylamido)pentanedioate (Glu‐MAC) is polymerized using diethylene glycol dimethacrylate as cross‐linker via the reversible addition‐fragmentation chain transfer (RAFT) technique to synthesize with pendant glutamate moieties. The mechanical properties of are examined by rheological study. exhibit higher value storage modulus ( G ′) than loss ′′) within linearity...
A series of copolymers with controlled monomer sequences are prepared via the reversible addition–fragmentation chain transfer polymerization tert-butyl carbamate (Boc)-l-alanine (VBA) and Boc-l-alanyl-l-leucine-conjugated styrenic (VBD) monomers l-alanine-appended maleimide (NMA). Monomer distribution in copolymer is examined by both 1H 13C NMR spectroscopy which eventually confirms an alternate placement different throughout polymer main copolymerization systems: VBA–NMA VBD–NMA. After...
Catalytic oxidation of benzyl alcohol (BA), p-chlorobenzyl (p-ClBA) and p-anisyl (p-OMeBA) in aqueous media has been investigated the presence two cationic surfactants, viz. cetylpyridinium chloride (CPCl) dodecylpyridinium (DPCl). The chromium(VI)-governed oxidations such aromatic compounds exhibit an unusual kinetics depending upon concentration CPCl DPCl. Both surfactants catalyzed at lower concentrations while retardation was noticed higher concentrations. catalytic inhibitory functions...
A green envelope of aqueous mixed micellar media composed CPC and Brij-35 catalyzes the diperiodatoargentate( iii ) governed oxidation isoprenol.
This study explores the catalytic oxidation of homologous alcohols (2-propanol, 2-butanol, and 2-pentanol) by diperiodatoargentate(III) (DPA) complex in a cetyltrimethylammonium bromide (CTAB) micellar medium. Notably, use a...
The formation of mixed micelles represents a promising strategy to enhance organic reactions in aqueous media, offering sustainable approach reaction optimization. This study investigates the catalytic oxidation cyclohexanol by chromium(VI) under acidic conditions at 27 °C with kinetics monitored using UV-vis spectroscopy. Three readily available surfactants, cationic cetylpyridinium chloride (CPC), non-ionic Brij-35 (polyoxyethylene (23) lauryl ether), and anionic sodium dodecyl sulfate...
Effect of polypyridine derivatives on chromium(VI) oxidation D-ribose in aqueous media was studied spectrophotometrically. The oxidized product D-erythrose detected by paper chromatography. promoters 1,10-phenanthroline, 2,2΄-bipyridine, 2-picolinic acid, and 2,3-dipicolinic acid accelerated the oxidation, whereas isomeric 4,7-phenanthroline, 4,4΄-bipyridine, 4-picolinic 2,6-dipicolinic did not influence oxidation. Formation Cr(VI)-promoter complex identified through fluorescence...
