1H NMR techniques in studies of transport of paramagnetic ions in multicellular systems.
نویسندگان
چکیده
Two different pulse sequences used in 1H NMR spectroscopy termed free induction decay amplitude recovery (FIDAR) and spin-echo recovery (SER) were applied to studies of transport of paramagnetic ions in multicellular systems. The molar relaxivity of several paramagnetic species (Fe3+, Co2+, Ni2+, Cu2+, Mn2+, MnEDTA2-, dextran-magnetite) in water solutions was measured at 32 MHz resonance frequency. Ionic transport was studied using Mn2+ and MnEDTA2- as models for cations and anions, respectively, and plant root tissue as a model of a multicellular system.

Synthesis and spectral characterization of naphthyldihydrazones derived from some 1,3- dicarbonyl compounds and their Ni(II), Cu(II) and Zn(II) complexes
The coupling of tetrazotised 1,8-diaminonaphthalene with 1,3-dicarbonyl compounds [acetylacetone,methylacetoacetate and acetoacetanilide] yielded a new series of tetradentate ligand systems. Analytical, IR,1H NMR and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bondeddihydrazone form. Dibasic tetradentate N2O2 coordination of these compounds in their [ML...

The carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through Bulk Liquid Membrane (BLM) and Supported Liquid Membrane (SLM) systems. The various membrane supports used are viz. PTFE, cellulose nitrate, and dialysis membrane and onion membrane. The amount of Li+ transported depends upon the stru...

The influence of paramagnetic Ln3+ ions on the NMR behaviour is investigated via a series of new isostructural lanthanide-containing cages with the general formula [LnTi6O3(OiPr)9(salicylate)6] (Ln-1, Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er). Compared to conventional coordination compounds containing Ln3+ ions, the peripheral ligands in Ln-1 are separated from the paramagnetic lantha...
متن کاملEnhanced sensitivity and resolution in (1)H solid-state NMR spectroscopy of paramagnetic complexes under very fast magic angle spinning.
High-resolution NMR spectroscopy for paramagnetic complexes in solids has been rarely performed because of its limited sensitivity and resolution due to large paramagnetic shifts and associated technical difficulties. The present study demonstrates that magic angle spinning (MAS) at speeds exceeding 20 kHz provides unusually high sensitivity and excellent resolution in 1H solid-state NMR (SSNMR...

Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...
