Chemically induced dynamic nuclear polarization (CIDNP) in the photoreaction of N-acetyl histidine, tyrosine, and tryptophan with 2,2′-dipyridyl and its dependence on the magnetic field
CIDNP effects for three amino acid-dye photoreaction systems (histidine, tyrosine, and tryptophan-dipyridyl in aqueous solution) are measured between 0 and 7 Tesla using a novel mechanical field cycling unit with fast digital positioning of a high-resolution NMR probe in a spatially varying magnetic field. The high spectral resolution allows to measure CIDNP patterns for different nuclear posit...
متن کاملNonlinear optical properties tuning in meso-tetraphenylporphyrin derivatives substituted with donor/acceptor groups in picosecond and nanosecond regimes.
meso-Tetraphenylporphyrin (TPP) and its two substituted derivatives (meso-tetrakis(4-cyanophenyl)porphyrin [TPP(CN)4] and meso-tetrakis(4-methoxyphenyl)porphyrin [TPP(OMe)4]) were synthesized. Their nonlinear absorption and refraction properties were studied using the Z-scan technique in the picosecond (ps) and nanosecond (ns) regimes. The open aperture Z-scan results reveal that TPP and TPP(CN...
متن کاملSynthesis, characterization and spectral properties of substituted tetraphenylporphyrin iron chloride complexes.
A series of substituted tetraphenylporphyrin iron chloride complexes [RTPPFe(III)Cl, R=o/p-NO₂, o/p-Cl, H, o/p-CH₃, o/p-OCH₃] were synthesized by a novel universal mixed-solvent method and the spectral properties of free base porphyrins and iron porphyrin compounds were compared with each other. The experimental results showed that the one-pot mixed solvent method was superior to the two-step m...
