Cholesterol appended bispyridinium isophthalamide dichloride (1) has been designed and synthesized. While compound 1 forms a gel in CHCl3, the cholesterol dihexafluorophosphate (1a) analogue that results from on anion exchange does not form any solvent combination. The chloroform of is pH responsive shows thermally activated ionic conductivity. It serves as medium for specific detection Ag+ ions over series examined cations. Compound 1a, other hand, acts selective Cl− ion detector by forming...
The diffusion constant and other electrical parameters of some LiTFSi salt dissociated PEO based polymer electrolytes has been estimated from the impedance spectroscopy data with reasonable agreement to that obtained PFG-NMR study.
Pyridine coupled mono and bisbenzimidazoles<bold>1–6</bold>are synthesized their gelation properties are examined in various polar as well nonpolar solvents. The gel states exploited metal ion sensing conductivity measurements.
A series of ionic-liquid-based nanofluids (ionanofluids) has been prepared by dispersing different wt % alumina (Al2O3) nanoparticles, covalently tethered with 1-n-butyl-3-(3-(trimethoxysilyl)propyl)imidazolium bis(trifluoromethanesulfonyl)imide [b((MeO)3Sip)im][NTf2], in 1-decyl-3-ethylimidazolium [Deim][NTf2] ionic liquid (IL) host. Thermophysical properties the pure-IL and its have studied using transmission electron microscopy, differential scanning calorimetry (DSC) vibrational...
A series of cholesterol-appended benzimidazolium salts 1–9 have been designed and synthesized. They explored in gel chemistry. The gelation the is dependent on nature counteranions. In addition, behavior gelators linked with presence both π-stacking cholesteryl motifs. Whereas bisbenzimidazolium salt 2 forms a dimethylsulfoxide/H2O (1:1, v/v) itself, under similar conditions, monobenzimidazolium 4 6 exhibit F– ions validate visual sensing F–. As an application, phase efficiently removes...
The dynamic melt crystallization kinetics of polyaniline (PAni)/poly(vinylidene fluoride) (PVDF) blends different compositions has been investigated to understand the influence PAni on heterogeneous nucleation and phase transition PVDF.
Abstract In this study, an organic‐inorganic hybrid polymer membrane is successfully designed and developed by grafting stearyl methacrylate (SMA) side chains onto the backbone of P(VDF‐HFP) copolymer followed blending with varying amounts imidazolium ionic liquids functionalized ZrO 2 nanoparticles. Different microporous gel electrolytes (MGPEs) are prepared immersing membranes into a LiTFSI salt‐dissolved liquid electrolyte. The membranes′ crystallinity, surface morphology, porosity,...
Abstract Cholesterol‐appended benzimidazole 1 has been synthesized. The gelation ability of the compound examined in different solvents and it exhibits strong with silver perchlorate DMF:H 2 O (1:1, v/v). Silver ion specific DMF: H highlights as excellent visual detector Ag + ions over a series other metal ions. Furthermore, silver‐induced gel shows thermally activated ionic conductivity due to movement within network.
The present article demonstrates an intensive study upon the temperature dependent current density (J)-voltage (V) characteristics of moderately doped polypyrrole nanostructure and its silver nanoparticles incorporated nanocomposites. Analysis measured J–V different synthesized nano-structured samples within a wide range revealed that electrical conduction behavior followed trapped charge-limited transition charge transport mechanism from deep exponential trap limited to shallow traps had...
The relaxation dynamics and charge-transport mechanisms of different benzene tetracarboxylic acid (BTCA)-doped polyaniline (PANI) nanostructures had been probed by the electric ac response samples from 42 Hz up to 5 MHz within temperature range 133–303 K. experimental results reveal that overall frequency-dependent transport properties these significantly depend on difference in morphologies obtained BTCA doping at concentrations. above study also illustrates common origin mechanism, PANI...
Molecular self-assembly assisted self-healing supramolecular metallogels of azelaic acid with cobalt(II)-, nickel(II)-, and zinc(II)-based metal acetate salts were successfully fabricated. Individually, N,N′-dimethylformamide dimethyl sulfoxide immobilized within these distinctly synthesized soft-scaffolds to attain their semisolid viscoelastic nature. Rheological experiments such as amplitude sweep, frequency thixotropic measurements executed for ratify gel features. The different extents...
Cholesterol appended pyridinium urea 1 acts as low molecular weight gelator in DMSO:H2O (1:1, v/v) showing distinct colour change the presence of aqueous solution KF well tetrabutylammonium fluoride and recognises F− specifically. In addition, this hydrogel is noted to detect Cu2+ Pb2+ ions over a series other metal exhibits good semi-conducting property.
